A Note on the Sources
The pages which have been
filmed are the best copies
available. Every technical
effort possible has been
made to ensure legibility.
PUBLICATION AND MICROFILM
COPYING RESTRICTIONS
Reel duplication of the whole or of
any part of this film is prohibited.
In lieu of transcripts, however,
enlarged photocopies of selected'
items contained on these reels
may be made in order to facilitate
research.
PATENT APPLICATION FILES
These files contain patent applications and related drawings, along with
correspondence between Edison’s attorneys and the U.S. Patent Office. Many
of the applications pertain to improvements in Edison’s phonograph. There
is also material relating to electric lighting and power, ore milling, motion
pictures, and various other technologies. A related set of application files for
Edison’s U.S. patents can be found in the National Archives (Record Group
241, Records of the Patent Office).
The draft notes and drawings in the Patent Series bear a close
relationship to the notes and drawings in the Notebook Series, many of which
carry inscriptions indicating that they were used in the preparation of caveats
or patent applications.
The following categories of documents have been filmed: draft notes
and drawings in Edison’s hand; files relating to Edison’s abandoned or
forfeited applications.
The patent application files have been filmed in chronological order
according to execution date, the date on which the formal application was
signed and witnessed. For Edison drafts, the dates appearing on the
documents are generally earlier than the formal execution date.
On the list that follows, each application appearing on the microfilm is
noted with its execution date; Edison case number; patent number (for issued
patents) or Patent Office serial number (for abandoned applications); and title.

1 y invention relates to an artificially formed material
which is an imitation of mother-of-pearl mid can bo usod for "
ornamental purposes for which that natural o> distance has

iridescent appearance of tho not hor-of- pearl. Tho iridescent
coloring of rtothor-of-poarl is duo to tho largo number of
minute wavy lines fornod by tho al tomato layers of Migio and
animal mattor of which tho substance is composed, andJUSasst
•f-wnd that tho depression botwoon those lines is quite
sufficient to form a perfect impression upon a plastic surface
against 'which the nothor-of-eoarl is pressed. Hot- only aro
tho linos thomsolvos accurately transferred but also the' '•
soculiar iridoscont appear onco . of tho mother- of rpoarl surface,
-or instance if a smooth shoot of, tin foil is made to re-
coivo tho inprossion, its motallio appoaranco is destroyed,
and it will havo instead tho appearanco of tho mother-of-pearl
surfaco from which tho impression was taken.
Such shoots of tin foil may then bo usod for any desired
ornamental purpose?, such as tho ornamenting of picture
frames, fans, otc., for which nothor-of- pearl has boon used,
.r-iy invention furnishing a good .imitation of mid a 'cheap
oubatitutc for the natural matorial. •

Convenient apparatus for producing this material, which
apparatus also forms .part of my invention is .illustrated in
the annexed droning.
Figure 1, is a perspective view and Figure :i, a c'-oss
section of the apparatus.
A i-. a stationary bod plate or frame and B is a travelling
plate sliding upon said bed plate. Sot in a frame a on the'
travelling plate is a shoot, slab or platen b of. mother-of-
pearl, which may if necessary be composed of several pieces
accurately fi-tod together, A roller o is placed on a shaft
d turning in boarings on tbo stationary bod plate close to...
the mother-of-pearl surface, so that when a shoe of tin- foil
o is placed on the slab b and the roller turned and the
travelling plate drawn along under tho roller, the tin-foil .is

There is nothing in this case but what is very old and

A brief reference to iridescent surfaces produced by
pressure against mother of pearl will be found in Tyndall's
Lectures on Light, delivered in America, at the end of Sec. II.
There is a fuller statement in Brewster's Optics, Chap. XV, page
139, of the London edition of 1863, where the author says:
"I have transferred the coloi
lead and tin by hard pressur*

This application has boon considered.
The claims cover both process and apparatus . In the recent
case Ex parte Herr 41 0 .0 . page 359, the Commissioner says; First,
“It must be regarded as settled by the very highest authority that
an apparatus and a process are separate. .and distinct inventions.”
•Second, “A claim for a machine or apparatus and a claim for the
process should be prosecuted in separate applications, and each,
when allowed, should be comprehended in a single patent.” Third,
“A process to be patentable must be wholly .independend of the ap¬
paratus” In accordance with this decision either the process or
apparatusclaims should be cancelled and the specification restrict¬
ed accordingly .

Claims 1 and 2 cover one process; claims 3, 4 and S, cover
another entirely different process, and claims 6, 7, 8 and 9,
cover apparatus. Action on the merits must be suspended until

This application has toeon roconeidoKsd as ainended.
The statement that by passing a strone current of electricity
through molten pig iron, the carbon can be burned out, needs sub¬
stantiation. The mere passage of the current would certainly not
have that effect, nor does there appear to be any oxyeen in pig
iron which could be liberated to combine with the carbon and burn
it; nor could the iron thus produced, oven if all the carbon were
removed, be termed "wrought iron".

Claims 1 and 3 do not seem to be warranted by the original
specification, which did not mention sub joc tire? the iron to any
"'Oxidizing influence whatever. . . .
. . These claims are rejected on this ground and on the ground
"that there is no invention in heating the molten metal by passing
an electric current through it over tiie ordinary puddling or pig
boiling process in which the metal is subjected to an oxidising
flame.
Claims 2 and 4 are rejected as covering an inoperative
' pjrocess. Unless the molten metal were exposed to the air or
some oxidizing agent it would be impossible for the carbon to be""
"burned out.

that the amendments presented in this application constitute

We presume the Examiner will not deny that
his decision in regard to departure from the original in¬

and that if the said tribunal should decide that no de¬

our appeal, it will be seen that tho first point on which

In view of this fact the Examiner is not justified in in¬

Piled June 4, 1887. on Appeal.
Examiners Statement.
Appeal is taken from a rejection of the fallowing claims:
"1. The method of making mall eable iron, which consists in
melting a mass of cast iron and maintaining the same in a liquid
condition in contact with the air or other oxidizing agent by pass
ing through the mass an electrical current of sufficient strength
to maintain the necessary temperature, whereby the carbon is burn¬
ed out, substantially as described.
2. The method of making malleable iron, which consists in
melting a mass of iron and maintaining the same in a liquid condi¬
tion and in a state of ebulition, whereby fresh particles are
brought to the surface and into contact with the air by passing
through the mass an electrical current of sufficient strength to
maintain the necessary temperature, whereby the carbon is burned
out, substantial! y as described.
3. The method of making mall eabl e iron consisting in heat¬
ing molten cast iron and maintaining the same in a liquid condition
in contact with the air or other oxidizing agent by a powerful
electric current thereby burning out the carbon, and then allowing
it to cool while in a powerful magnetic field^ubstantiall y as set
forth.
4. The method of making malleable iron consisting in
placing molten cast iron in a mold and exposing it to the air or
other oxidizing agent passing an electric current through it of
it, over the ordinary puddling or pig boiling process in which the
metal is subjected to an oxidizing flame.
Claims 3 and 4 stand rejected for that each is an aggre¬
gation of a non-pa tentaVj] e process of decarbonizing iron with an
old method of cooling.

.’••EUOKAHPtJU OP ARfiUMTWT FOR APPTjIOAMT .
The claims in this application are rejected in part on refer¬
ences, and in part on the p-oirnl that they involve fi* departure a fr om
the invention as originally described, .and that certain of the
claims cover mere age regat. ions. The claims involve two principal
. i doas ; first, the passage through molten cast iron of a current
of electricity of ouch quantity as to keep the iron in a liquid
condition until the carbon in the iron is burned out; and second,
allowing the iron thus treated to cool in a magnetic field. The
References relied on by the Examiner show that it is old to pass a
current through molten cast iron for the purpose cf affecting the
molecular structure of the iron, or for the purpose of purifying
the iron by eloctrolytie action. The references also sho?/ that it
is did broadly to allow molten iron to cool in a magnetic field.
The patent most nearly approaching applicant’s invention ap¬
pears to be English patent 2712 of 1S72. in tils patent is de¬
scribed the passage of a current from a magneto-electric machine,
preferably a Gramme machine, through molten iron in a mold. The
mold is said to be one inch doop, two feet six inches wide, and
six feet long. An eiectrodo connected with the two terminals of
the generator is placed in each end of the mold. The patent re¬
fers to the current used as a powerful current .
• (1)
It does not.
however, intimate that tho current io of sufficient quantity to
maintain tho heat of the molten iron at tho boiling point. The
whole tenor of the specification if said patent indicates that
the current acts el ectrolyti'cally on the molten iron. This is of
course vary different IVom the action, by heat. It is also inti¬
mated in the patent that the heat may be maintained by a suitable
furnace. It is evident that with a mold of the size above men¬
tioned filled with molten iron a current of very great quantity
(as distinguished from a current of great intensity) would be re¬
quired to have any appreciable effect on the temperature of the
iron. It is exceedingly doubtful whether an ordinary commercial
machine such as lam were on the marb.et in 1372. would produce a
current of the proper character to produce tho effect describod by
.Mr. -Edison.
In English patent 474 of 1373, the current cloatfly acts to
chemically decompose or remove substances from the iron. The
chemical reactions are fully set forth.
In English patent 470 of 1873, furnace heat is relied on and
not electrical heat.
We do not find in any of the other references any clear state¬
ment to the effect that the temperature is maintained, and the car¬
bon tarn ed out of tho molten iron by means of an electrical eurresit
The references, therefore, fail to meet tills bmnch of the inven¬
tion.
Tho Examiner holds tliat by amendment a departure from the
original description has been introduced. In the speci fi cat icn
as filed, it was stated that a current of sufficient quantity was
(2)
passed through the iron and served to bum out the carton. ■ it was
not specifically stated that the surface of the iron res in con¬
tact with the air. Figure 1 of the drawing, however, clearly
shows tliis to be the Ciso. 0 is clearly described as the molten
cast motal in the mold, and the surface of the metal is ontiroly
uncovered. The allegation of the Examiner that Figure 2 shows
that the mold is not open, is therefore incorrect, as also is his
allegation that Figure 1 merely shows the electrodes projecting
into an ordinary mold. In amending the application, we stated
that the -iron in the mold is exposed to tho "air or other Oxidiz¬
ing agent. Of course, there i3 no foundaticn in the specification
or drawing for any oxidizing agent other than air, but the ex¬
pression "air or other oxidizing agent" was used in a generic
sense to cover any oxidizing atmosphere': surrounding the mold.
It is submitted that the use of the description above referred to
as to the effect of the current, that is.bthat it burned out the
carbon, is sufficient to warrant the introdunti on of a statement '
|bhat the molten iron was oxposed during treatment to the air, since
it is well known that the oxygen of the air, or its equivalent,
is essential for such action.
Claims 3 and 4 involve the idea of burning out the carbon as
above described, and then allowing the metal to cool in a powerful
magnetic field. Y/o submit that the first part of tho process does
combine in a patentable sense with the second part. Certain of
tho references cited show that it is an old idea to pass a cur¬
rent throi^gh molten iron to rive a certain direction to the mole¬
cules of the iron. The passage of a pourerful curroit such as
described by applicant cannot fail to have a decided influence of
(3)
"this- general character, and the iron is subjected to the socmd
step of the process while it is in the host possible condition for
the action of the magnetic field, and when a partial arrangement
of the molecules of the iron has taken place.
The Examiner states that no invention is involved in heating
by tchx a current instead of by an ordinary furnace. vre submit
that the simplicity and cheapness of the apparatus requirod in
applicant's process, the ease with which the degree of heat can be
regulated by the mere regulation of the generator, and the fact
that small quantities of iron may be .treated,, .as well as large
quantities, v/hich is not the case in ordinary Ihrnaces, as well as
°thor considerations, are sufficient to establish the fact of in¬
vention in the procoss.

I Decision of Board
-in-
Edison, No> 340.199, Manufacture of Wrought Iron. _
V/e soo no objectionable new matter or departure from
the ^original specification, except the words "or other oxi¬
dizing agent" in the 1st, 3rd and 4th claims, vhich should bo
eliminated, other things being correct, and the invention be¬
ing found patentable.
The whole case turns upon the burning out of the car¬
bon by the use of the electrical current.
If the first tvro claims be tenable the others follow.
If not, they fail, as there is nothing in the employment of
both steps, it being conceded that the last stew is old'.
In regard therefore to the 1st and 2nd claims it is
not important that we consider any of the references except
Johnson’s British patent (2712 of 1872)-.
It is conceded that the means shown by Johnson could
be employed to effect the same result by the same mode’. But
it is denied that the means are so enployed, and the same mode
disclosed to secure the same result.
It is true that Johnson sets forth his invention for
effecting the purification of oast iron, malleable iron &cW
to consist in passing the electricity througi it in the same
way as proposed by applicant, "the chief object" being to
effect purification and does not specifically set forth the
burning out of the carbon.
Yet we think that the disposition of the carbon must
necessarily be inferred from the moans employed and the pro-
I cess described. Ho speaks of employing a current sufficient:
to fuse the iron, and that by keeping it up "of suitable du¬
ration and intensity" while the metal is in this state of fu¬
sion certain elements of impurity mentioned, including carbon,
will be separated into tvro groups "each proceeding to a dif¬
ferent polo"w
He further says "By various arrangements of the mode
I of operation depending on the position and nature of the elec¬
trode, the intensity and duration of the currents, and the si¬
multaneous intervention of suitable mechanical or' chemical
actions, I am enabled to retain in the cast iron either a’
j| poition or ohe whole of the sulphur, phosphorus, carbon &c-. ,
to eliminate them entirely, by bringing them to the surface
|| of tin bath where by a powerful oxidation, they are caused to
| disappear.
That is they are destroyed or burned out by the heat.
And further he says by employing an air blast to
| "produce a flurfaoo agitation and of rendering more active the
|| oxidation nfxthx of the impurities? .that is burning them.
And again he says "These operations" - to produce
Isoft wrought iron -- "would be carried out"in a similar manner
to that of refining on Bessamer's process" - the only differ¬
ence being the means for producing the heat.
That both secure the same result from electrolytic
| act ion and heat is apparent.
We see no good ground for disturbing the action of
jthe Examiner and affirm his decision-.

Dear Sirs:-
I return herewith the papers re Mr. Edison’s appli¬
cation No. 719 on Manufacture of Wrought Iron, which accompanied
your letter of 21st instant. Mr. Edison does not wish you to
take an appeal in this matter: nor does he wish a patent taken
out on the claims allowed.
Yours truly,

however that this application seems takeover the identical in¬

\la believe the oath recently filed in this
application to bo fully responsive to the spirit of the rule
I requiring acknowledgment of foroign patents . Every patent on
this invention of which applicant or his attorneys have any
knowledge, and all which could bo found by a considerable
search, are acknov/'l edged in the oath. It happens that
neither tho applicant nor tha attorneys liavo records which
sliou all the countries in which some of these early inventions
wore protected, and the information could be gained, if at
all, only by a good deal of trouble. It is certain that
there is no patent which would expire earlier than the patents
acknowledged in tho oath. It is well settled that it is not
positively necessary for foreign patents to be acknowledged
prior to tho grant of a patent. Xhe patent is limited
whether they are acknowledged or not. We therefore request
that the oath be received as sufficient, and that the case be
Given action on its merits. It is not true that it is essen¬
tial that tho o’ath have a positive otatemont in regard to the
foreign patents as a condition precedent to action on the
merits; many cases are examined without such statemont. So
long as the statement is put in before tho patent is actually
issued, that has been considered sufficient.

Room No . .221. ’ _ Commissioner of Patents.
The argument filed nee. 5,’ 1889 requesting a
reconsideration of the requirements of official letter mailed Dec.
8, 1887 seems to have no bearing on such requirement. The re¬
quirement ask.ed a compliance with the rules' and fonn contained
therbin, which make it necessary that appli cant shall state in
the oath where he resides arid that he shall use the terms "any
country", instead of the- term'b|any foreign country. The argument
above is to the effect that the R. S. section: 4887 "provides that '
the "U . S . patent shall haggled to' the term of a prior existing
•foreign patent." and that; Applicant has made oath that no foreign
pats, exist on the invention claimed.-" and he therefore asks
that the. present oath be considered as sufficient evidently such
•assertions even if Granted to be true in fact, have no. bearing on
the requirements as to applicants place of residence and as to
the words "Any Country" instead of "any foreign country" as set
forth above. But the Examiner in addition cannot admit the above
assertions to be true in fact especially the last . .
Mo record is found in this case wherein applicant swears that
"no .'foreign patents exist on the invention claimed." and it is
thought applicant in framing this argument has confused this case
with his other pending case;ji no. 253,80 0 filed Oct. 19, 1887.
The oath filed in this application merely states that the
alleged invention lias not been patented with applicants knowledge
or consent in "any foreign country" and even this statement was
traversed in substance in official letter mailed Dec. 8, 1887 r.:
wherein it was intimated that this invention has been patented in
England No, 1644 of 1878 and such patent was in fact taken out
by applicant. The question as to whether or not this application
has become abandoned under rule 171 is not now raised since at
present, the Examiner fails to see how applicant can overcome
the disclosures made in.ihis English patent above. The case
howeirarrifetaiidsuas it did upon the first official action dated Bee.
7, 18S7 and the requirements therein made are repeated. If
applicant objects to a compliance he can consider the case as in
condition for a petition to the Commissioner.

To all whom it may concern:
Be it known that I, Thomas A. Edison, of Llewellyn Park,
in the County of Essex and State of Hew Jersey, have invented
a certain neve and useful Process for Duplicating Phonograms,
(Case No. 743), of which the following is a specification.
The object I have in view is to produce a practical
process for the duplication of phonographic records, so that
the new art of phonographic publication can be,, established.
Generally I propose to construct a suitable matrix pre- .
ferably in metal and by its use mould duplicate phonograms
with the phonographic records thereon such phonograms or the
surface thereof being preferably constructed of a material
too hard for the satisfactory indentation thereof by the
phonograph recorder, but the duplicate phonograms may be
made of a softer material.
Eor the construction of the matrix I preferably employ
the process of vacuous deposit described in my application No.
118942, filed January 28, 1884. The original phonogram
is preferably constructed with a surface of wax or a similar
material. This is placed in a suitable phonograph and the
phonographic record produced thereon. The phonogram so
impressed with the phonographic record is placed in a high
vacuum in which an electric arc continuous or discontinuous
is produced between electrodes of metal, or in whi ch metal
vapor is otherwise produced. The electric arc produces a
vepor of the metal of which the electrodes are composed, which
(t 2
vapor, or a metallic! vapor otherwise produced within or
supplied to said chamber, is deposited on the indented surface
of the phonogram forming a layer of metal thereon which
follows accurately all the indentations of the record however
minute, owing to the highly comminuted condition of the metal
deposited. The phonogram while the deposit is taking place
in the vacuum chamber is revolved slowly by a suitable power
connection, and this is especially necessary y/hen the form of
the phonogram is cylindrical which it preferably is. The
vacuous deposit is continued until the layer of metal is
sufficiently thick, v/hen the covered phonogram is removed
from the vacuum chamber and is further covered by a more
rapid process to give strength and body to the covering. A
further covering of metal may be produced by electro-plating
a metal upon the vacuous deposit in the usual manner of
electro-plating, or the vacuous deposit may be backed up by
casting upon it type metal or other metal or alloy having a
lower fusing point than the vacuous deposit, or this may be
done after electro-plating upon the vacuous deposit, .or the
vacuous deposit may be backed up by a cement, or gum, or by
plaster of Paris, but a metal backing is preferred'.'
The material of the original phonogram is then dissolved
off of the metal covering leaving in the case of cylindrical t
phonograms a hollow metal cylinder or one internally faced
with metal carrying the phonogr aphic record in relief upon its
inner surf ace . This metal cylinder is then split longitudi¬
nally by a very thin saw into a number of parts, say for
illustration three parts, which are suitably mounted upon
levers, so that a mould is formed which can be closed to
receive the material to be moulded and opened to permit of its
be ing t aken out .
The duplicate phonograms are produced by means of this
mould by pouring therein and preferably around a suitable
I core placed in the mould, suitable substances such as wax,
or wax- like material, resin, or plaster of Paris, the material
being preferably too hard to be satisfactorily indented by
the phonograph, or the duplicate phonograms may be made by
taking sheets of smooth material like waxed paper or tin foil
and pressing them upon the surface of the mould by a plunger
or otherwise, the sheets being afterwards backed up by a wax,
resin or cement. The latter way of making the duplicate
phonograms is especially applicable to flat-surface phono¬
grams although it may be used for phonograms with cylindrical
surfaces.
Instead of employing the vacuous deposit for first cover¬
ing the record of the original phonogram, I may employ the
process of electro-plating for this purpose. A specially
prepared plumbago of exceedingly great fineness might be em¬
ployed to cover the wax like surface as a basis for .the elec¬
tro-plating, or gold-leaf, or silver-salts reduced by chemical !
reagents to the metallic state migit be used for the same
purpose. But the plumbago and gold-leaf do not bring out
the fine vibrations and produce rough reproductions while tie
silver -salts do not run well on the wax-like surface.
The vacuous deposit however adheres uniformly to the
wax- like surface and reproduces the record with great per-
Ifection, and hence I prefer to employ it in the production
[of the matrix.
The invention is illustrated for convenience in connec¬
tion with a cylindrical phonogram.
In the accompanying drawing forming a part hereof, -
Figure 1, is an elevation of an original phonogram:

thin vacuous deposit thereon:

Figure 5, a sectional view of the divided mould or matrix:

a. The metallic vacuous deposit is shown at c, and the
further backing preferably of metal is shown at d.

having the phonographic record in relief. 0 is the dupli¬
cate phonogram, produced by the mould and having a surface e.

II do not claim the specific invention of duplicating
phonogr sgihic records or constructing matrices therefor wherein
the phonograph record is first covered by a vacuous deposit,
that specific subject-matter being reserved for a separate
application for patent which I propose to file.
Y/hat I claim, is:
First : The process of duplicating phonograms carrying
a phonographic record, consisting fir3t in indenting the
original record upon a phonogram, second constructing a
matrix or mould of such original record, and third producing
duplicate phonograms from such matrix, substantially as set

to the COMMISSIONER op patents
With reference to the requirement of the
Examiner that the process described in this case should bo
practically demonstrated before action on the merits,we
have to say that a specimen has been filed in applicant's
case, Serial No. 118,942, filed January 28, 1884, now pending
before the Examiner .Room 149 of the Patent Off ice, which
specimen consists of a phonogram having a record and a met*
coating applied- by the process set forth in this application
It is believed that this specimen will furnish sufficient
proof that the reoord is not destroyed by the application
of the metal in the manner referred to.
With reference to the objection made to
the oath in this case we submit that such oath is sufficient
to comply with the requirements of Section 4887, Revised Stat¬
ues. The statute provides that a U.'s. patent is to. be
Limited to the term of a prior foreign patent. Applicant
laving made oath that he has no foreign patent for the in-
rention.it is not seen how anything further can be required

An examination of the specimen filed in room
149 in connection with applicants other pending case No, 118,942
shows that none of the former objections have. been removed, and
the specimen seems to confirm such objections. The nature of the
specimen is such that the Examiner fails to see that applicant
could have filed it with a serious intention of complying with the
requirements made, and this case is believed to be dead. Such
question is not now raised, however, and such requirements are
finally in sisted^pvv, Applicant must either comply or petition the

APPLICATION OP THOMAS A. "EDISON
PROCESS for duplicating phonograms
PILED JANUARY 5,1838
SERIAL No. 259,895 (SERIAL NO. 743)
TO THE COMMISSIONER OP PATENTS, -
s I R:-
It is not understood what the Examiner's
objections are to the specimen referred to in the last Of¬
ficial letter. The questions raised as to the process in
letter of March 14, 1888 were whether the electro vacuous
deposit could be evenly produced and whether the heat of
the vapor would not injure the record. The specimen shows
a most even coating of metal upon a phonogram bearing a
sound record and seemed to us therefore to fulfill every re¬
quirement. It is impossible to make any intelligent ac- ■
tion in reply to the Examiner's criticism since the grounds
of his objection are not stated. If the reasons why the
specimen is thought to be defective are furnished us we will
endeavor to furnish suitable explanation thereof.
We desire to protest against the placing
on record of such statements as that contained in the last
letter of the Examiner to the effect that he considers the
application as probably having been abandoned. It is not seen
how such a statement can serve any useful purpose. If|tho
Examiner believes the case to be dead he should so state
and should refuse to act further upon it- since if it is
dead it is out of his jurisdiction. If however he believes
it to be still alive( which it appears from the fact of his
action upon the merits, must be his true opinion Jit seems to
us far from being his duty to place upon the record an irre¬
sponsible insinuation to the contrary.

I
New Jersey and Pennsylvania Concentrating Works.
I Be It known that I, Thomas A. Edison, of Llewellyn Park,
in the County of Essex and State of New Jersey, have invented
a certain new and useful Improvement in Phonograms, (Case
I No. 74-4), of which the following is a specification:
■ The object I have in view is to produce a practical
construction of duplicate phonogram!-., which can be made cheaply
and can be used to reproduce the recorded sounds indefinitely.
This I accomplish by constructing a phbnogram of material ltoo
liard to be satisfactorily indented by- the action of the, voice
and producing the phonographic re cor'd upon its surface fr"3m a
metal matrix having the record in relief.
Generally I propose to construct a suitable matrix,
preferably in metal, and by its use mould duplicate phonograms
with the phonographic records thereon such phonograms or the
surface thereof being constructed of a material too hard
for the direct indentation thereof by the phonograph recorder.
Por the construction of the matrix I preferably employ
the process of vacuous deposit described-' in my iEp’pii cat ion
No. 1189.42, filed January ,28, 1884. The orifgi-rgal phono¬
gram is preferably constructed with a surface <&f^|(£x or a
•similar material. This is placed in a suit able-^phonograph
*
and the phonographic record produced thereon. j
The phonogram so impressed with the phonographic record
is placed in a high vacuum in which an electric arc con¬
tinuous or discontinuous is produced between electrodes of
metal or in which metal vapor is otherwise produced'. The
electric arc produces a vapor of the metal of which the
2
electrodes are composed, which vtpor or a metallic vtpor
otherwise produced within or supplied to said chamber is
deposited on the indented surface of the phonogram forming a
layer of metal thereon which follows accurately all the in¬
dentations of the record however minute, owing to the highly
comminuted condition of the metal deposited. The phonogram
while the deposit is taking place in the vacuum chamber is
revolved slowly by a suitable power connection, and this is
especially necessary when the form of the phonogram is cylin¬
drical, which it preferably is. The vacuous deposit is con¬
tinued until the layer of metal is sufficiently thick, when
the covered phonogram is removed from the vacuum chamber and
is further covered by a more rapid process to give strength
and body to the covering. A further covering of metal may
be produced by electro-plat ing a metal upon the vacuous deposit
in the usual manner of electro-plating, or the vacuous deposit
may be backed up by casting upon it type metal or other metal
or alloy having a lower fusing point than the vacuous deposit,
or this may be done after electro-plating upon the vacuous
deposit, or the vacuous deposit may be backed up by a cement,
or gum or by plaster of Paris, but a metal backing is pre¬
ferred. The material of the original phonogram is then dis¬
solved off of the metal covering leaving in the case of. cylin¬
drical phonograms a hollow metal cylinder or one internally
faced with metal carrying the phonographic record in relief
upon its inner surface'. This metal cylinder is then split
longitudinally by a very thin saw into a number of parts say
for illustration three parts which are suitably mounted upon
i; 3
levers, so that a mould is formed which can be closed to re¬
ceive the material to be moulded and opened to permit of its
being taken out'.
The duplicate phonograms are produced by means of this
mould by pouring therein and preferably around a suitable
core placed in the mould, suitable substances such as wax or
wax- like materials, resin, or plaster of Paris, the material
being too hard to be satisfactorily indented by the phonograph,
or the duplicate phonograms may be made by taking sheets of
smooth material like waxed paper or tin foil and pressing them
upon the surface of the mould by a plunger or otherwise, the
sheets being afterwards backed up by a wax, resin or cement,
the vfliole producing a surface that cannot be satisfactorily
indented directly by the phonograph. The latter way of mak¬
ing the duplicate phonograms is especially applicable to flat
surface phonograms although it may be used for phonograms with
cylindrical surfaces.
Instead of employing the vacuous deposit for first cov¬
ering the record of the original phonogram, I may employ
the process of electro-plating for this purpose. A specially
prepared plumbago of exceedingly great fineness mif^it be
enployed to cover the wax-like surface as a basis for the
electro-plating, or gold leaf , or silver-salts reduced by
chemical reagents to the metallic state might be used for the
same purpose. But the plumbago and gold leaf do not bring
out the fine vibrations and produce rough reproductions while
the 3iiver-salts do not run well on the wax-like surface.
The vacuous deposit however adheres uniformly to the wax- like
surface and reproduces the record with great perfection, and
14
hence X prefer to employ it in the production of the matrix.
The invention is illustrated for convenience in connec¬
tion with a cylindrical phonogram. In the accompanying
drawing forming a part hereof

Figure 2, a cross section of the original phonogram with a
thin vacuous deposit thereon:

phonogram dissolved out:
Figure 5, a sectional view of the divided mould or matrix:

A is the original phonogram having a relatively soft wax
t wax-like surface a and the backing of harder material b..
he phonographic record is produced upon the surface a. The
letallic vacuous deposit is shorn at c, and the further backing
preferably of metal is shown at d.
B is the divided mould produced as has been stated and
having the phonographic record in relief. 0 is the duplicate
phonogram, produced by the mould and having a surface e
indented with the phonographic record and of harder material
than could be practically or satisfactorily indented directly
by the phonograph.
The duplicate phonograms are preferably cylindrical and
hollow for li Witness and to permit them t o be placed on
phonographs having revolving phonogram cylinders.

I do not claim in this application the process of dupli¬
cating phonograns shown and described herein, since this is
claimed in my implications , Serial No. 259,895, filed January
5, 1888, and Serial No. 262,428, filed January 30, 1888.
What I claim, is :
First: A duplicate phonogram carrying a phonographic
record and constructed of a hard material not enable of be¬

set forth.
Second: A duplicate phonogram carrying a phonographic

Commissioner of Patents.
r filed discloses the existence of
|a prior foreign patent which #ias already expired and as the Examine
|unde retands the language of Sec. 4887 the tern for which a
|domestic patent can be granted has expired also. If there are
*any reasons against this view they must be part of record.
i
'The oath is defective also in that it contains the qualifying
phrase "so far as he is able tci.istate". Rule 46 requires that
, applicant "shall distinctly state under oath whether he has or has
not" obtained foreign patents a fact which he inust be informed
Mahout better than any one else. The case awaits an explicit
declaration in this particular in place of the equivocal one
presented.
It is observed that in the first action in this case the
“AfiiSwm were rejected on a referenc e,and that at the expiration
of four years no attempt has been made to overcome that reference.

be it known that I, 'Thomas A. Edison,. a citiion of tJ.o United
Stales, residing at Uoweilyn - Park in the County of Hssex and
State of New Jersey, have invented a certain new and usef
Improvement in Processes of Making Phonogram Blanks (Case
No, 750 ) of which the following is a specification;
As described in ray application for patent, Case No
747< serial number I prefer to make my phonogram bla
wholly of a wax or wax-like material so that such blanks w
have throughout their mass the same co-off icient of expans,
under variations of temperature. I have met with some a.iti
culties in the waking or such phonogram blanks, uue t,o the
it
oessive contraction of the material, which. is the object o
this invention to overcome. .
In moldini; the wax phonogram blank I have found th;
if the wax be permitted to become entirely cooled while a
in the mold and surrounding the core Uial t.he contraction <
the wax is liable to cause it to crack. lienee after -.ppui
the wax into the mold I permit it to set sufficiently to j
tain its form and while it is yet hot (X remove the core si
tliat the .further contraction of the wax is permitted without
tlie danger of cracking. TJie wax phonogram blanks when take
from the molds are sometimes irregular in shape and side due
to the excessive contraction of the material and hence it he
30i i«s necessary to make -the bore of the cylinder tmie as wo]
the cylindrical

| TO THE COMMISSIONER OP PATENTS,
s i r:-
A specific reference is asked for the
I fii-st claim in order that applicant may be enabled to act
intelligently in the matter.
As to the 2nd claim.it is denied that the
patents referred to show that the process claimed is one
in common use . It is quite evident that in these patents
the core is not withdrawn until after the metal is cooled.
In fact the patent of Balding specifically states that tho
core is withdrawn after the casting has cooled and shrunk.
Applicant's claim is definitely for removing the core before
cooling so as to allow contraction after such removal. In
view of this, reconsider at ion of this claim is asked.
V/e con see no reason why the word ''mold¬
ing" should be changed to "forming" in this claim. Wo shall
bo glad however to make the change if the Examiner has any
good reason for requiring it and will inform us as to what
such reason is.
As to the 3rd claim, since it is not shown
that the first stop of the process is not a novel one, the
ground of rejection apparently fails. It is not understood
why the steps of this claim do not properly constitute a
- 2 -
method or process . She tv/o stops enumerated are applied suc¬
cessively to the material with the ultimate result of pro¬
ducing a finished phonogram blank. Reconsideration is asked
on this point also.
Respectfully,

In view of the above amendment we desire to ask

SERIAL No. ?,m, 923 (EDI SON ' S No. 750)
TO THE COMMISSIONER OP PATENTS,
In vtw of -che fact that a new reference was
ci-^ed in the last Office letter we desire to present our
reasons for believing that the reference does not antici¬
pate the cl a ins and to solicit a favorable re -cons id scat ion
of the last Office ae’tion. Certain difficulties have been
found in the forming of phonogram blanks owing especially
to the fragile nature of the material employed, as fully de¬
scribed in the speei fi cation . To obviate these difficulties,
and especially the cracking of the blanks, applicant hit on
the method claimed in this case. It appears frt>m"0ook's Gun¬
nery" cited that in casting guns a core is used which con¬
sists of a barrel which is -wrapped with rope and then cover¬
ed with a composition. When the molten metal is poured into
the mold the heat consumes the rope so that the barrel of
the core is entirely detached from the casting, and this is
or may be withdrawn before the casting is cooled, but the com-
position which is a part of the core remains within the bore
of the gun .This is surely a different thing from that cov¬
ered by applicant's claims. The entire purpose and effect of
the procedure is different in the two cases.
In view o.t the above facts ,an allowance of the clains
is requested.

EXAMINER'S ANSWER.
Claims appealed aret
1. The process of molding phonogram blanks of wax, consisting in molding the wax
upon a core and removing the core before the wax cools, wherby cracking of the blanks
is avoided, substantially as set forth.
2. The process of making py lindrical .phonogram b lanks of- wax .-consist ing in
molding the wax cylinder upon a core and removing the core before the wax is cool*
and then putting the wax cylinder upon it3 external and internal surfaoes to males it
true, substantially as set forth.
Reference in Cook’s Gunnery, Jno. Y/iley & Sons, H. V. 1880, pages 176 to 187.
The object of this invention is to over-come the difficulty in molding wax
phonogram blanks, duo to the excessive contraction of the material, such as hereto-
fore resulted in cracking the blank*
This is done by removing the core, after the wax has set sufficiently to retain
it firmly, but while it is yet hot.
The reference described a process of casting guns, which process is not altered
(in a patentable sense) , by substituting wax for metal.
In paragraph 473, page 182 of the reference, the core is unmistakably removed
before the molten metal has become cool.
In claim 2, it is further stated that the cylinder, after the core is removed
is cut upon "its external and internal surface to make it true."
.... Thefle steps are fully described in paragraphs 478, 485 and 489 of the reference,
and are done in order that the gun cylinder may bo made true.
It wan held that applicant had merely followed the old method of casting guns,
in malting his wax cylinder, and the olaims were rejeotdddfor that reason.

On Appeal
t;o the
Board of Examiners in Ohinf
T'’oh applicant.
I'i'ha invontion involved in the application on which
this appeal is taken consists in a raothod of making phonogram
blanks or record cylinders, consisting in molding molten vrax
or wax-like iraterial around a core, allowing it to stand a
very short time to set suff iciently to enable it to retain its
shape, then removing the core while the molded wax is still
hot and allowing the cylinder thus formed to cool and contract
with the core removed. Tho invention also consists in the
same procedure followed by the cutting of the cylinder on its
inner and outer surfaces to make them true, so that the inner
surface shall properly fit the phonograph cylinder, and so
that the outer surface shall bo entirely regular, thus enablirg
the recording and reproducing points to act successfully.
Appli cant '3 phonogram blanks are composed entirely of
wax of uniform consistency, as distinguished from' blanks hav¬
ing a paper or other 'tough base with a coating of wax, such as
are sanetimes used. Tho main object of making blanks in
the first form is to obtain a large thickness of wax so that
many records may be made on the same cylinder by shaving off
the surface after each record has been used as much as desired.
Much trouble has. been experienced in making this form of

MEMORANDUM OP ARGUMENT
I blanks, os pec tally on account of the fragile nature of the 'm
or wax-like material via ad, and be cause of the largo coeffi¬
cient of expansion thereof, since when formed in the usual
vray, that is, in the way that casting or molding is ordinarily
done, by pouring the molten material into the mold and allow¬
ing it to cool for a considerable time, the cylinders fre¬
quently bocame cracked and rendered useless by the large con¬
traction due to reduction of temperature. To overcome that
difficulty applicant invented the method of molding the blanks
defined in claim 1. While the method is exceedingly simple,
it is also efficient, and it is well settled that the patenta¬
bility of an invention is not negatived by the fact that it is
simple. This, in rather a point in favor of patentability.
Turning now to the references cited by the Examiner, -
the three United States patents show absolutely nothing having
any material bearing on applicant's claims. They show merely
collapsible cores for uso in casting in the ordinary manner.
It docs not appear from any of the patents that the cores are
removed before the article cast has shrunk by cooling. The
collapsible cores are used primarily to allow their ve naval
after such contraction has taken place. One of the patents,
Hal ding 100,585, distinctly says, "Vfhen the casting is cooled
around the mold and shrunk after its fashion, the core is con¬
tracted and withdrawn." From the Examiner's answer it ap¬
pears that he doos not care to have said patents considered
in connection with the claims since lie says nothing about
t hem .
The reference to Cook's Gunnery is ncO)ett er than the
patents. This publication describes the casting of large gure

n such manner that they "dll not crack and still to have a

pated by the fact that metal castings have been cut to give
hem true surfaces .
For the reason briefly indicated, it is submitted that

To all whom it my concern:
Bo It Known that I, Thome A. Edison, a oitiaon of tho
United State o, residing at Llewellyn Park, in -the County of
Essex and State of Now Jersey, have invented a certain now
and uooful Improvement, in Processes of Proparing Phonogram . .
Blanks, (Cnoo No. 754), of which tho following is a specif iw ::v
cation. .
i y invention rolatos to tho preparation of phonogram
blanks having surfaces of wax, with the object of improving
tho articulation of tho phonograph.
This I find can bo accomplished by banishing with a.
ho ate d burnishing tool the wax or wax-liko surface of tho
phonogram^ The effect is to smooth out tho tool marks pro¬
duced in turning tho surface to a true cylinder and to roduco
greatly the scratching noise heard in tho recorder and con¬
sequently made a part of tho record which 'is reproduced by
tho reproducer.
I provide the phonograph itself with the heated burnish-
ing tool as well as with ,the cutting, tool* the former acting1
after the latter upon the surface. Both tools are adjustably i
carried by tho holding arm or guide sleeve of tho phonograph
so that they can bo brought intoittproper relation with tho
surface and made to work at tho same timo upon it. Tho
burnishing tool may bo a pioco of platinum wire hoatod by
_.tho electric current or it may bo a nioco of wire which is,.
hoatod by a small- alcohol lamp and conducts tho heat to tho
• "burnishing point of tho tool. .
Tho process of preparing the wax surface of tho phono-
gram^ia of course independent of mounting tho heated burnlsh-
ing tool upon the phonograph itself. Tho wax surface may bo
burnished after it is first turned off and before placing the
phonogram blanks upon the phonograph, but since 3C provide my
phonograph with a cutting tool I also prefer to place the
heated burnishing tool directly upon the phonograph.
In the accompanying drawing, forming a part hereof
Figure 1, is an ond elevation of the phonogram cylinder and
phono gram^with the holding am and the cutting
and burnishing tools carried thereby:
Figuro 2, a top view with the holding arm broken away:
Figuro «3, a view similar to figuro 1 showing a modified form
of the heated burnishing tool; and
Figuro 4, a view similar to figuro 2 showing tho modified
form of burnishing tool.
A is tho revolving phonogram cylinder. 13 is tho travel¬
ling holding arm mounted on the guide sleeve 13' and carrying
tho recorder and reproducer the am and sleeve bo inf; fed
laterally by a load screw on the shaft of tho phonogram
cylinder as will be well understood. Tho frame C carried
by tho arm B roots upon tho guide rest D it boing adjustably
supported thereon by a sot screw <a.

PROCESS OP PREPARING PHONOGRAM BLANKS,
j PILED JANUARY 30, 1888
SERIAL No. 262,431.
TO THE COMMISSIONER OP PATENTS, -
s I R:-
In the above case a re-consideration is
requested. The Ground taken by the Examiner in rejecting
the case is that the invention claimed is anticipated by
the procesa of waxing boot heels. It is submitted that such
process is in no way analogous to the process claimed by
applicant. The object of burnishing the wax surface of a
boot heel is to press the wax into the leather and produce
a gloss on the surface. With phonogram blanks the specific
resuit is to produce a surface free from irregularities and
thereby to prevent the scratching noise of the recorder
which becomes a part of the record and is reproduced in
the operation, of the reproducer. It is submitted that ap¬
plicant has produced an important improvement in the art of
making phonogram blanks, which has a new and useful result
in that art and that nothing which may have been 1®% own in
the art of making boot heels could havo suggested the diffi¬
culty or the means of remedying it which this application
describes. If the Examiner believes that there is any anal¬
ogy between a boot heel and a phonogram blank and insists
upon this ground of rejection we have no doubt of the result
of an appeal to a higher tribunal.

| argument that he holds that a process having one object in view

/same process having another object in view as the burnishing of
boot heels. The Examiner thinks it very clear that the reverse
is true and holds that after one wax surface is burnished as that
of a boot heel that it does not require invention broadly to
^burnish any other wax surface, as that df a phonogram blank. Of
course it is well known that burnishing is common in, a number of
arts, and this ease could be rejected on many other references,
but the above is thought sufficient.

TO ALL W H n r.t i p y, y CON C E g
3e it known that I, Thomas A. Edison, a oitiisn of the United
States, residing at Llewellyn Park, in the County of Essex Mid
State of New Jersey, have invented a certain new and useful
Improvement in Processes of Making Phonogram Blanks, (case. 756
of which the following is a specification;
The object I have in view is to produce a method or
process of making molded cylindrical phonogram blanks from wa;
which will enable a better blank to be produced,^ will les¬
sen the expense of manufacture.!;, ' and will prevent the liabil.
ity of the blank to crack while cooling in the mold.
Cylindrical phonogram blanks formed of waxes, gums,
and mixtures of the same by pouring the waxes while in a melt
ed state into the mold, contract enormously while cooling, and
this is especially true of those mixtures suitable for phono¬
gram cylinders. lienee it is a very difficult matter to mold
tubes or cylinders from such waxes or mixtures. The groat
shrinkage causes the cylinders to crack notwithstanding the
various devices employed to prevent it, and the molds for
this purpose are complicated and expensive and require exoert
manipulation.
lb overcome these objections,! provide a mold with a
dividing strip running lengthwise thereof on one side, so that
when the molted wax is' poured therein the continuity of the
ojflinder will be broken on one side; that is to say the wax
cylinder will be molded with a slit or opening on one side. *
On coo 3 in;, the cylinder done not contract inwardly and thug
in
brook, bub in contracting draws away^bobh dirodtiono from tho
dividin'.; atrip without tho alight© at dnngar of distortion or
craokin;;. Tho wax may bo loft in tho mold until entirely
cool and nay '! hnn h* rorovod* An it eoraoa from tho mold it

upon its external and internal surfaces as doccribod in my

Serial No. of application referred to nn page 2,
should be inserted in the specification. Both claims are rejected
for want of patentable novelty. It being held tbabeono invention
to apply an old process to a new material . The process is the
same with all substances to which it may be applied, and the
Statutes do not give a monopoly of the right of such application
to a particular composition. Patents 161238, Joyce, No. 143326,

to be old when applied to wax as well as to metal .

SERIAL No. 262,433.
TO THE COMMISSIONER OF PATENTS, -
S I Rj-
In the above case the following amendment
is submitted:
- !• The prooess of making Cylindrical
phonogram blanks consisting in molding or forming such
blanks upon a mandrel froiA hot wax or wax like composition
with a break or opening on\one side, sod permitting contrac¬
tion of the material to take place by the spreading of such
break or opening and subsequently closing such break or
opening by similar material to complete the. cylinder, sub-
2. The process of making cylindrical
phonogram blanks consisting in molding or forming the blank
on a mandrel from hot wax or wax like material with a break
or opening on one side, permitting the contraction of the
material by the spreading of such opening, then removing the
cylinder from the mold and then closing the break or
cylinder by filling it with melted wax, substantially as sot
It is submitted that applicant's invention
which relates to the formation of a cylinder from wax, is
distinct from the matters set forth in the patents cited as
-3-
neferenoes. Some of those rolate to the manufacture of leacl
Pipe in which the matter of providing for contraction does
not arise, the point in these oases being to leave an opening
through which the core of the mold can be reached to remove
it. In the Joyce patent the molding of hot wax does not
form a part. In that patent the wax is in a flexible sheet/
cold, and is rolled into a cylinder ,tho edges of which are
then united . The matter of providing for contraction in
molding, which is applicant's object, does not arise in this
process.

TO THE COMj'II SSIONER OF PATENTS,
! sir:-
Wo desire to request a reconsideration in
| this application in view of the following points:
The examples referred to in the last of- •
fioe letter of instances in which wax or wax-like surfaces
| have been polished, do not appear to us to bear on thio oaso
becauBO articles said to be thus polished are so entirely
i dissimilar from applicant's. Applicant’s use of the
polished surface is not analogous to prior uses and would
not be suggested by thorn. It would naturally be supposed
that a phonogram blank as smooth as it would be after being
I I turned off by a sharp cutting tool, would bo in first class
condition for receiving the Bound rocord, and it was not an
obvious thing to see that it was the minute irregularities
of the surface of the blank that introduced imperfections
into the record and thus into the reproduction of the sound,
and that by using a burniBhed blank the trouble could be
largely overcome.
Curtis says, in hia "Treatise on the Law
of Patents" 4th edition 1873, page 55,
I "In order to escape the objection of a
double use, it is necessary that the now oc¬
casion or purpose to which tho use of a known
thins is applied should not be merely analogous
to the former occasions or purposes to which
tho soma thing has boon applied.”
Under this principle, which is well established, we think
the caso should be allowed.
It -would soon that the fact that the claim
was originally said to bo allowable and was after-wards ro-
jactea, would indicate that the Examiner was in doubt as to
the patentability; if so, tho doubt should bo solved in ap¬
plicant's favor.
Allowance is requested.
Respectfully,
Attorneys for Edison.

In order to enable the Examiner to under¬
stand wherein applicants alleged invention differs from the
gr aphophone cylinders previously patented, and wherein the burnish¬
ing process constitutes the alleged not obvious improvement, a
specimen blank made in accordance with the principles set forth
is insisted on. vhe final disposition of the question as to
whether or not the burnishing feature is patentable is delayed
until an actual inspection of the article can be had.

Dear Sirs:-
In your letter to Mr. Edison of 15th of August last
you informed him that in his application 763, the Examiner in¬
sisted on having a sample of the phonogram blank in order to see
the effect of burnishing the wax surface.
A sample phonogram blank has been prepared and I send the
same to you herewith by special messenger. In accordance with
your suggestion, one half of the blank has been burnished and
the other half left unburnished.
Yours truly,

Th0 blank forwarded on the 10th inat. r/aa
whole when it was sent and was carefully packed, and we do not
undo rst and 'wh^ it was broken.
It seems to us unnecessary for the Examiner to require
another specimen. Of course the pieces of the specimen sent
can be examined and the difference between the smooth parts,
that is the parts which have been burnished, and the rougher
parts, which have not been burnished, can be readily seen al¬
though the blank is not whole, and, as we understand it, all
that the specimen was desired for was to show the effect of
burnishing.

Dear Sir,-
Your application No. 763, which contains a claim on
a phonogram blank having a burnished wax or waxlike recording
surface, stands finally rejected on two patents to Tainter and
patents of your own which show Wax phonogram blanks, and in
rejecting the claim on such patents, the Examiner states that
burnishing is a common expedient wherever a polished or smooth
surface iq desired, and that it is also ooianon in connection
with waxed surfaces as in smoothing over boot-heels, . for in¬
stance. We think there is a fair chance of sucoess before
the Board, and wish to know whether you care to take an ap¬
peal. In connection with this mattjrfrW^rish tf> remind you
that the application on the fcrboessyST burnishing phonogram
blanks was abandoned in acoo^dahtte with your Ins true tions ,
that case also having b\^6 finally rej^Yted by the Examiner,

Be it known that I, Thomas A. Edison, of Llewellyn Park,
in the County of Essex and Stato of Bow Jorsoy, havo invented
a certain new and useful Improvement in the Method of Separat¬
ing Metals from their ores, (Case Mo. 773) of which the follow
ing is a specification.
Hy invention relates to a mothod of procoss by which gold
or othor non-magjiotdc metals may be separated from their ores;
and my objoct is to enable tho process of magnetic separation
to be applied to such non-magnotic materials.
In accomplishing this I take the minglod mass of part¬
icles of precious motal and of quart#, rock, sand or other
non-conducting and non-mu: -notic material and I deposit oloctro-j
lytically upon each metal particle a small quantity of iron
or other magnetic motal; in other words I attach to oach
particle of non-magnotic material a particle of magnetic
material. IThon this has boon done tho mixture of metal
parti cl os and non-motalllc particloo con be readily separated
by tho magnetic process. I --.rofor to employ a magnetic
separator such as is shown and. described in my prior patonts .
and applications, in which tho minglod particles aro allowed
to fall in a stream past tho polos of an el octroemaigiet,
whoroby tho trajectory of tho magnetic particles is altered
and they are made to fall separately from the non-magnotic
onos which continuo in a vortical direction.
: I havo found that if particles of gold, or othor motal
aro placed in a hath containing a solution of a salt of iron
and with positive an! nogativo electrodes of iron, and a
• 3
current is passed through such lath, an iron deposit is pro-
ducocl on one jiido only of each of such' particles, and in a
short time sufficient magnetic material will bo added to the
gold to pormit the same to bo readily affoctod by a magnoti
: iy invention is illustrated in the accompanying .drawing.
Figure 1# is an illustration of the principle of the invention:
figure f$, is a cross section and Figure J^a top view of the
electrolytic cell such as J; prefer i to use in practice; and
figure d, is a view of the preferred form of magnetic
separator.
IG
In figure U, A represents a coll, Da solution thoroin of
it salt of iron, a a' positive mid negative electrodes of iron
connected with a source of oloc tricity, represented at 0, and
‘j> b metal particles placed in the coll between the electrodes.
-i-hftve/Vfound that when any piece of metal, no matter how
small, is placed in this 'way between the electrodes of an
oloctrolytic coll, there will bo a deposit produced upon one
sido thereof only. There is a convergence of the conducting
linos from the poorly conducting
liquid to the highly conducting motal , and a sharp difference
of potential botwoon tho liquid and tho metal at the points
where tho current outers and loaves' tho metal, so that thoro
must bo a doposit of motal on the sido whore tho curront
enters tho particle.
in figure 1 the convergence of tho lines of conduction
is indicated, and tho heavy shading on one side of each of the
particles b b (whose si::o is of course exaggerated in tho
drawing) indicates tho doposit on such particles.

In figures^ and i|, 13 represents a tank of iron or other

This application has been considered.
The Examiner would like to satisfy himself that the' process
described is practicable, and to that end would suggest that the
applicant loan to the Patent Office his apparatus, giving full
directions as to the composition of the solution, strength of
current, etc., and furnish- samples of metals and metallic ores, and
also, samples of metals or ores which have been coated with iron
by applicant's process.
The claims seem to be unnecessary repetitions of the same

TO TJiK COMMISSIONER OP PATENTS!
SIR!
We should be glad to comply with the Examiner's
requ ost that applicant's apparatus should be lent to him for
oxp orimontiii purposes but unfortunately the apparatus weighs
a ton or more and requires a largo space in which to set
it lip, so that it is quite i:'.ipractica:b]gto do so. We however
do not see the necessity of exp erimont by the Patent Office
on this matter. If the Examiner intends to take tho ground
that the process described by applicant is inoperative lie
should sot forth fully his reasons for so believing and wo
shall then be glad to furnish proof to the contrary. If how¬
ever there are no reasons for believing tho invention to bo
inoperative, notion on tho merits of the case is asked*
As to tho objection that the claims are repeti¬
tions of the same process, it seems to us that there ure
dear distinctions between all tho claimsiTho second claim
adds to tho first, the separation" by magnetic attraction. Wo
noto that the Examiner holds that there is no combination
between the depositing and the separating steps. Those two
steps seem to us to be parts of the sumo complete process
of separating ores. The separation cannot be accomplished
without the depositing and this fact seems to make it clear'
tlsat a patentable combination exists between them. The

TO AIL mm IT MAY OOHGPRH!
Bo it know n that I, THOMAS A. EDISON, a citizen of
tho United States, residing at Llewellyn Hark, County of F.s-
sqx and State of New Jersey , have invented a cortain new and
useful Impro vomert^for Producing Duplicating Stencils , of
which the following is a specification.
Tho object I have in view is to produce a simple and
efficient process fur preparing duplicating stencils, from
which a largo number of copies can bo printed^ by rolling a
printing ink thereover, upon sheets placed beneath it. This '
I accomplish by coating |f§* impregnating a porous material
through which ini: is readily transmitted, such as Japanese
dental paper, with a substunoe impervious to ink such as par-
afine. The sheet so pr.- pared is laid upon a suitable back¬
ing, such as a shoot of unsized paper or a surface of wood, '
and then by writing on such sheet with a smooth-pointed sty¬
lus the purufine coating will bo removed from tho shoot at
tho points of writing without impairing tho texture of tho
shoot itself. Tho compression of tho parafino-impregnated
shoot between tho stylus and the support or backing causes
tho parafino to be removed from the sheet wherever the stylus
has passed over the shoot without impairing tho texture of
the sheet itself .thus leaving tho fibrous texture of the sheet
exposed at such points so that ink can be pressed through it
while the sheet at other points is impervious to ink.^par-
afine coating or filling is removed from the sheet by ex.-
prossion in all directions, it being partly ploughed up by
the smooth point of tho stylus , partly pressed laterally into
the coating or filling that remains on the sheet tind partly
made to adhere by nrossure to tho suppbrt or backing upon
v/hich the sheet is placed. This stencil sheet is then
placed, in a suitable frame and copies are printed therefrom
in tho manner described in my patent No. 180, 8R7, granted
August 8, 1876.
In tho accompanying drav/ing forming a part hereof,
the figure represents a sectional view of tho pan.s as the
parafine sheet is beinj written upon by tho smooth pointed
stylus!
A, is a sheet composed of porous material through
which ink i3 readily transmitted, such as Japanese dental
paper, v/hich i3 coated or filled with a substance impervious
to ink, such as parafine, whereby the sheet is made impervi¬
ous to ink. This sheet is placed upon a suitable backing, B,
of wood or paper, and the matter of which duplicates are' de¬
sired is written upon the shoet A by means of tho smooth
pointed stylus Cj -the parafine being removed from tho
t-r-
sheet by express! onAin all directions by tho point of tho
stylus .^parafine being^exprossed laterally into the body^
^parafine which remains on tho sheet, ^eing ploughed up by tho
point of tho stylus and^being caused to adhere to the backing
or support B. This is done without impairing the toxturo
of the sheet, and by the pressuro of the stylus without the
surface or
using of a puncturing^ instrument or the use of a choikical
agent; the sheet is thus made a stencil sheet from which
copies can be printed as before explained.
WHAT X CLAIM AS MY INVENTION IS’.
FIRST; The process of making duplicating stencils,
which consist in coating or impregnating a sheet of porous
material, through which ink is roadily transmitted, as Japan¬
ese dental paper, with a substanco impervious to ink, as par-
»fine, and then removing such coating or filling therefrom
at the points or lines of writing without impairing the text¬
ure of the sheet , substantially as and for the purpose speci¬
fied.
SECOND! The process of preparing duplicating sten¬
cil sheet S/.wlu oh consist in placing the sheets on a suitable
support or backing, and in removing the coating or filling
therefrom in the desired form by prossure with a writing in¬
strument without the use of the punoturing surface or instru¬
ment, or the use of a chemical agent, substantially as de¬
scribed.
THIRD: The prooees of preparing Btenoil sheets
from a shoot of such thin and w-frrTrly porous texture as to be
open to the transmission of ink, coated or filled with a gum
or waxy surface, which consist in placing said sheet upon a
bearing surface, to which such substance will adhore by
pressure thereon with a v/r'iting instrument , and thoroby so
far displacing said substance and transferring it to the
bearing surface by adhesion as to leave the lino of impres
o
sion on' tho, sheot open to the free transmission of ink, su
starit iallyl. as doscribod.

3 I r:-
I have boon informed by certain of the parties there¬
to that an interf ercnce has been declared between applica¬
tions of Larkins, Brodrick, Kin b or ami saicl Dick, the subject
ma tter of wiiich is as follows:
11 The process substantially herein described of pre¬
paring a stencil or transmitting printing sheet which con¬
sists in placing a sheet of porous material through which
ink is readily transmitted coated with a water-proof sub¬
stance upon a backing having a broken or uneven surface to
which said water-proof coating under pressure will adhere,
then applying pressure to portions of said shoot by a writijg
or printing instrument and subsequently removing the stencil
all qo t from said backing.4*
The invention made the subject of this ir.terf erenoo
seems to us to be shown and described and substantially
a 1 aimed in the above named application. Such appli cation
describes the use of a sheet of porous paper coated with ink-
proof material placed upon a backing to whioh such material
will adhere under pro ssu no, applying pressure' by a writing
instrument lin'd then removing the stencil sheot from the back¬
ing and this is covered by applicant's claims^ more especially
by the third claim.

'Hie only question may be aa to the expression "havirg
a broken or uneven surface", Tho uneven nature of the sur¬
faces is merely a question of degree, tho objeot being to ha to
surface to which tho material will adhere. Applicant de-
’ paper and sta-tos :fcr ar^~ — -c-
soribes -the use of wood <
p a P e r.^vsjiocessarily s»e muro or loss uneven, they being
described as surfaces to which tho material adli ares *, and he
especially refers to the use of unsized paper which clearly
i an uneven surface.
Applicant has filed proof of invention prior to the
earliest of the applications in the interference, and there
ms to be no reason therefore why he should not be isado a
party, l^have to ask therefore that this may be dona, and it
is hoped that action will bo made as speedily as possible,
and before any further proceedings are taken in the inter¬

TO TUB COMMISSIONER OP PATENTS, -
S I R:~
By a com tun i cation dated December 28, 1888, ap¬
plicant requested that his application above named Should
be admitted to an in tor for on co understood to bo ponding""
botwoon applications of Brodrick, Klubor and Harkins, which
interference I undorstmid to be No. 13132. By letter of
March 20,1880 the Offico denied this roquost , the reason
I'ivcn being that in interference No. 18129 applicant had op-
portunity to prove priority of invention as regards certain
other subject matters nnd that the subject matter of No.
13133 being a more limited one there was no reason for in¬
cluding him in that interference . I am nnablo to see the
force of this argument. The invention defined in the issues
of No. 18183 is very clearly shown and described and nub-‘
slant! ally claimed in the above named application, and tho
fact that applicant in involved in an interference with the
same parlies on other subject matters does not seem to mo
to have fuiy bearing on tho question of hiB admission to "
this case. As was clearly explained in letter of Dooomb'or
28,1888, tho fibrous material of broken or uneven surface is
fully described in this application which describes the
use of wood or paper for backing and particularly of un¬
sized paper which evidently has an uneven surface.
In another lottor dated Docomb-' r 88-1888 appli-
cimt request od admission to interference No. 1 31 31 now pond¬
ing between application a of Harlrins, Brodrick.Rlnbor and
0.io!e and this request was refused for the some reason as '
above stated. The above remarks an ply also to this inquest.
In view of this I repeat the request for admission'
into interferences No. 13131 and 18138 and ask a ro ■consid¬
eration of the official action of March 80,1880 which it is
hoped will be made as speedily as possible In order that

TO ALL WHOM IT MAY CJONOEPN •
Be it known that I, THOMAS A. EDISON, a citizen' of
the United States, residing at Llewellyn Park, County of Es¬
sex and State of How Jersey have invented a certain new and
, • (&42M, 1>&0 77 f)
useful improvement in Gas Incandoscents , r? "-high. the ful '
for, which I have obtained a patent in Prance, No, 180,810,
l 3 0 i f i 0 Cl c i , . n . bearing date August 25th, 1879,
or which the following is a specification,
llio ob.TCut I nave in vi gw is to produce a gas in¬
candescent, which, while retaining the high refractory quali¬
ties of the earthy oxides that have heretofore been employed
will have great advantages over such oxides / in that it will
bo curable of being raised to a light giving incandescence
with a much less heat, or smaller f lamo , and henco will bo
more economical in the consumption of gas.
This I accomplish by the employment for tho gas
incandescent of a decomposed salt of an earthy oxide. Such
a docomposod salt hus struotural characteristics of groat
lightness and porosity, which differ widely from those of
an oxide obtained in any other way.
to produce tho gas incandescent^ I decompose by heat
a salt of any suitable earthy oxide, such as an ao'otato of
-an; oxide, the form being given to tho incandoscont body
either before or after the decomposition. I employ for this
, suon as limo, zqrconia or
purpose any of tho earthy oxides,
Dollars as the first fee payable thereon.
<ers are duly filed, and your application for a patent xoill be taken up fo
\ be duly advised of the examination.
Very respectfully,
Commissioner of Patents.
letter dated June 6, 1888, accompanying this appli¬
cation is similar to the pne commented on in examiner's letter
in the companion case, No. 276,386.
The Specification does not completely set forth the
"best mode" of producing tho incandescent, nor a complete opera¬
tive incandescent, nor does it claim such; but merely the product
of a commonplace chemical operation.

APPLICATION OF THOMAS A. KOI SOU
GAS INCAN OKS OKi ITS
FILED JUNE 7,3.88?'
SKRIAL No. 87(3,385 (UNISON'S No. 778)
TO THE COMMISSIONER OF PATENTS,
8 1 R:"
In reply to Official letter of June 25,1888,
the following is submitted
The abandonment of the old application by fail
Iure to prosecute eliminates one of the difficulties present
ed by the Examiner.
The specification sets out the two necessary
steps for the production of the pas incandescent , viz;
(1) the decomposition of the salt of the earthy oxide by
heat, and (2) giving the material form. The latter the
specification states may be done before or after the decom¬
position. These 'two steps are all that is necessary. The
mounting of the gas incandescent after it is produced 'Boas'
to subject it to the heat of a gas flame may be done in
many ways which any mechanic would supply and which are
supplied by the art in connection with the uso of other '
gas inc an descents, The. mounting has nothing to do with the
process of producing the gas incandescent itself. That re¬
lates to its use after it is produced, and the art tells how
to use it.
The sii ec if i cation sets out suitable earthy ox¬
ides. That being the case, and applicant being the first
to use the decomposed salts of any earthy oxide as a gas in-
-8-
I candescent his claim need not repeat the oxides by name.
.Chat is not necessary in order to rJistinguioh ovor the prior
art. If other earthy oxides than those specifically named
should be found on an investigation of their characteristics
after decomposition of thoir salts by heat to bo suitable
ior the purpose .they should be embraced by applicant 's
broad claim. Specific patents might possibly, be granted
ior the use of these newly investigated oxides, but appli-
cant.who has discovered the use of a new class of materials
for this purpose, should not bo limited to the particular
species which he has investigated.
-he references evidently do not meet the claim. They
arc either not gas incandeseents at all, or arc not the de¬
composed salts of earthy oxides. A mere laboratory test for
the presence of an acid in a material, which may be carried
on by the same process certainly does not forestall an indus¬
trial process for producing a commercial product.
The Examiner's statement with respect to the law
applicable to patents for processes is not understood. The
I result of a process is always its. product, and how there can
bo "a novel result other than the 'product 11 does not strike
one, at least not. at the first glance. The Examiner's law
with respect to patents for products would seem to place ap¬
plicant's product upon a footing of patentability.
A re-examination is asked.
Respectfully,
Attorneys for Edison.

| T1:ie S'rsneh patent to Gauden.of record, describes a gas
| lnoandescent element made of a decomposed salt of an earthy oxide,
| viz: nitrate of calcium or nitrate of magnesium. The nitrate, in
| a heated condition, is deposited upon the inner surface of a gold,
silver, or platinum vessel, of the shape which it is desired to
give the incandescent , by rubbing or painting the nitrate thereon
with a brush. During the operation of depositing the nitrate, the
vessel is maintained at a cherry-red heat, so that each layer or
I coating of nitrate deposited by the brush is deconposed and reduced
to an oxide. When a sufficient number of coats or layers have
been deposited to give the required body or thickness to the incan¬
descent, the surrounding vessel is removed by any suitable means.

You will recollect we filed for you two applications
for patents on Gas Incandescents . These two oases stand fi¬
nally rejected and further action will have to be by way of an
appeal to the Board. We have not examined the reference,
which is a French patent, very oarefully, because we did not
know whether you cared to go to any further expense in the
matter. If you wish, we will examine the reference carefully
and advise you before taking an appeal. Kindly let us hear
from you so soon as possible, for if any action is to be taken
it must be done before July 5th.

Vo all whom it ma,y concern:
j Vo it known that l, Vb.onas a. Mison, a citizen of tho
I'WtOd States rosidin at T.lowoHyn >kvfc, in tho Pounl y of
j ttrnox and «t«to of How Jersey, have invented a certain now
an! useful Improvement >.r Phonographs (Paso 'o. 78:}}, of which
tho following i" it specification.
Vh.o olrjoct I ho/ - in view is to on able tlv transmission
of phonograph records from olnco to nlaco and th.o rooroduction
of tho sounds noon i$f?n”ont machinef^ rihv: necessitates the
construction of a >hono>raoh and a obonogrron blank which will
enable tho phonogram blank to bo removed. from tho machine
iiuoon which tho record in produced and to bo adapted to bo'
| ar; in olacod upon the same machine or another machine and hp.vo
! the sounds reproduced from th.o record. I have constructed
removable phonof^m blanks in various shapes, as flat plates
with tho rocord formed in a voluto line, and ns cylinders with
the record describing a spiral lino upon their external sur¬
face.
I prefer to use cylindrical phonogram blanks mndo entire¬
ly or having a recording surface made of wax or a wax com¬
position, Those blanks have cylindrical outor or recording
surfaces and are preferably provided with tapering boros Which
fit upon phonogram cylinders having a corresponding taper.
Tho blanks hold themselves in position by tho friction of
tho tapering surfaces.
:>ly invention, howovor, is not limited to any particular
foiTO of •oho blank or of the blame carrier or any special form
j of tho phonograph apparatus, 3inco the feature of the remov-
jl iJii'-io am : : oarrying on :li>r. free end a toothed block g, which
jj ongagos with a fine screw thread h cut on tho shaft : bot::oon
j tho cylinder <■■ and' wheel !>. :>1io recorder il ir. r»i*o '/i-loci with,

provided \.*.L *cii a diaphragn k mid, a reproducing point k*. 'iho
reproducing point is uoproxirautoly about half as vide as tho
recording point, so that the reproducer vri.ll bo $ von a margin
of adjustment in adjusting it to tho track of the record raado
by tho recorder of the -.ano or a different machine. d is a
phono:;, ran blank, which is a cylinder of wax having a tapering
boro and aduptod to bo slipped on the phonogram cylinder fl
and to bo readily removed therefrom, the friction of tho sur¬
faces being sufficient to 'retain the blank in position. Yho
center b is mounted on a swinging am <H$o permit the phono¬
gram blank to bo placed upon or romoved from the phonogram
cylinder or bionic carrier.
A ph.nno'-rum folanlf being placed upon tho cylindor tho
shaft rel cylindor are rovolvori and tho npootnclo framo is
a^E 30 ®fl t’*> bring tho rocordor into nonition for operation;
thon by adjusting tho screw d, tho recording point will bo
lowered until it touches tlao surface of tho Phonogram blank.
As tho machine is illustrated tho rocord in started at tho
.left hand end of tho blank and is finished at tho rirht hand
end. A propor speaking tube is attached to tho recorder
and the matter to bo recorded is spoken into it, the revolution
of the phonogram cylindor being continued and tho recorder
being fed forward by tno food screw h, VJhon tho rocord is
completed tho rocking holding arm is thrown back into the"
position shown in figure 2, and the cylinder may bo stopped '
revolving or it may continue to revolve. The phonogram'
blank is slipped off of tho cylinder and a now blank put in
its place when an additional wee or d can bo made. Those
blanks having tho rocords thereon may bo transmitted to a
distance and placed upon othor machines or they may bo olaced
upon the same machine. Y/hon it is dosirod to roproduco the
sound one of the blanks with a record upon it is placed upon
the phonogram cylindor and the spectacle frame is swung to
bring tho r oproducer into operative relation with tho rocord;
tho screw d is then -adjusted until tho reproducing point
touches the surface, when by -adjusting tho screw f tho lateral
position of tho reproducing point is varied until it is
dotomined by listening that the best adjustment has boon ob¬
tained; by elevating the rocking holding am by the finger e"
the reproducer can bo sot to any part of tho record or sob"
back to repeat any portion of tho rocord which has not boon"

In tho above entitled application
wo horoby appeal to tho Honorable Hoard of Bxominors-in-Ohiof
from tho decision of the Primary Rxnminer contained in- his
lettor . of November bfch, 1888, finally rejecting tho claims
presented.
Our reasons of appeal aro as follows:
1. Tho Kxaminor erred in deciding that applicant's
patent No. 888,416 anticipates the invontion claimed, since
said patent does not show or doscribo or claim said invontion.
2. Tho Hxnminer erred in deciding that applicant' s
patont No. 886,074, anticipates the invention claimed since
the present application was filed before said patent was
iosuod, and said patont relates to a different invention from
which tho present invontion is properly divisible.
An oral hearing is asked.

- Application of Thomas A. Edison
For Improvement lib Phonographs Filed July 7,1888 Serial No.
279,881
Before Hon. Board of Examiners in 'Chief on Appeal.
Memorandum of Argument
for Edison,
Five claims were filed in this case each of which sound
finally rejected and from such rejection this appeal in taken
The references relied upon by the Examiner in rejecting
these claims are two patents issued to applicant #882,418
dated May 8,1888 and #286,974 dated July 81,1888
The first of these patents issued about two months
before the present applicantion was filed.
The second patent was issued about three weoks after
the present application was filed. •
The first patent #882,41(3 neither describes now shows
the invention applicant discloses .
It is true a tapering phonogram holder is shown but no
reference is made to it in the specification which would
indicate that it was to be used to hold a removable phono
gram blank. Nothing was disclosed to the public which would
lead it to suppose such was the case.
In Hood vs Boston Car Spring- Co. 21 Fed Rep 07 Judges
Gray and Nelson say:
"A patent is not invalidated by statement in
an earlier publication .unless those statements are full and
definite • enough to inform those skilled in the art how to •
put in practice the invention now patented. *
There is nothing in this reference either statement or
drawings, full and clear enough to inform those skilled in
2
tho art how to put in practise the invention now sought to
be patented. On this ground the reference cited 1b without
force.
The invention covered by this patent is for a portion of
the machine entirely distinct from that which is claimed in thi
application. They are not necessarily used in conjunction with
each other since the feed movement of the patent nay be used
with any character of blank or blank carrier.
The second patent cited having issued subsequent
to the fiTitjjf: of this application is also without force as a
reference*
It i3 a well settled law that a patent , the application
lor which is filod prior to the grant of another patent
which describes but does not claim the invention of the later
patent is not effected by the earlier patent.
In Singer v Braunsdorf Y Blatchf 521 it is laid down that
"a patent is not invalidated by the fact that the invention
claimed' in it was described .but not claimed , in a patent
granted subsequently to the making of the application for •
the patent secondly issued '.but before it was granted"

Application of Thomas A. Edison,
j Improvement in Phonographs.
Piled July 7, 1388.
I Serial Wo. 279,321.
Brief for Applicant on appeal to the Commissioner of
Putents in Person.
This application contains several claims, each of which
includes, aa an element, a removable phonogram blank. The
object of the invention is to enable the blank after a record
has been placed upon it, to be removed so that it can be used
for reproduction at tume future time on the same or a differ¬
ent onstrument. The Primary Examiner rejected the olaim on
reference to two of applicant’s own patents. The Board of
Bxaniners-in-Chief confirmed the Examiner as to one of these
patents, and reversed 'him as to the other. Consequently
there is now before the Commissioner only one reference - that
is to say, applicant's patent No. 336,974, dated July 31,
1888.
It v/ill be seen that the present application tfas filed
before the patent r/asi issued, and therefore as is now well
understood, there is no question of abandonment or dedication
to the public. . Itis well settled that a patent is not in¬
validated by inscription inthe invention in a patent granted
while the application fo» the second patent was pending in. the
Patent Offioe. See Singer v. Braunsdorf, 7 Blatoh. 521.
Graham v. McCormick, 11 fed. Hep. 722.; Holmes Electric Co. v.
Me trppolitan Burglar Alarm Co. 13, Jed. Hep/ 264.
The Board,hdwever, took the ground that the application
claims the same invention as iB oovered by the patent, and
4
I
! 3
jin the/patent is not a claim for such blank.
I ^e Both cl a in is for a special arrangement and conotruc-
jtion of removable phonogram blanks, but is evidently for a dif
i ferent invention from that claimed broadly in the application.
The 87th claim iB probably that which .comes the closest
to the application, ainoe it covers specifically the arrange
ment of removable phonogram blanks which Lb shown and desorib-
jod in both thapatent and the application. Of course this
| construction is covered by the broad claim of the application
i but the fact that one c.i aim is broad enough to cover ttndin-
I elude another, does not lead to the conclusion necessarily
| that they are for the same invention, and different oily in
j scope. In the present case it seems clear that such is not
the correct conolus ion, for there are other forms of removable
phonogram blanks besides that covered by the patent, and these
are covered by -he broad claim of the application. One such
other form is referred to in the application: It is, namely/
that of a flat plats with the record formed in a volute line
and applicant distinctly states that he is not limited to shy
special form for the removable phonogram blank.
Applicant's patent No. 437,424 dated September S&, 1890,
shows another form of removable phonogram blanks, and still
another form is shown in applicant's patent No. 400,650, dated
April 2, 1889. Mow all these different forms are oovered bp
the broad claim made in this application, andthati claim might
have been made in any one of them; but it s«ems entirely /prop
er to malts such broad claim in an application by itself. The
faot that applicant selected the particular form shown in pa¬
tent No. 386,974 to illustrate hds generic invention, does not
■
I alt rtf* the faot that suvh invention ie indapendentor the par-
!j tioular fonn in whioh it is embodied. It is oiear that the
II
j invention of a removable phono-gram blank did not necessarily
J| involve the invention of the special fonn shown in the pa-
jltBnt. These invention may have readily been made at differ-
!ent times . The same aot of invention did not necessarily
^ roduce them both, ahd they are therefore properly to be ooneid
ered as distinct and independent inventions.

SSBIJJ, BO. 279,321 ' ^ t!” B°“'4 °? 1" Chief.
FILED JULY 7, 1888 :
Brief of Argument for Applicant/
THe invention, being a simple one, is clearly indicated
by the terms of the claims and need not be further described.
The object of the invention is, to produce an apparatus
in which, after a phonogram record has been made, the blank
may be removed, so that it, ma* be used on a different phono¬
graph, or may be replaced on the first phonograph, at any time
desired.
The only referance relied on by the Board of Examiners. in
Chief is applicant's own patent 386,974,, July 31, 1888, grant
ed about three “eeks aftex’the filing of the present applica¬
tion. . ,
The Examiners in their decision say, that "That patent
contains a complete disclosure of everything covered by the
present claims, and some of its claims- relate to the same
subject-matter. The difference is, that the scope of the
claims is different."
We do not admit that the difference between the oliims
of the application and of the patent is merely a difference
of scope. Most of the claims of the patent could not by any
possibility have been made in this application, since they
embrace novel features not shown or described in the appli¬
cation. ThesefeatureB are in the nature of distinct improve
ments on the apparatus illustrated in this application, al¬
though the application/on which the patent was granted was
3
oifio claim to a single well defined construction, not at all
essential to the use ofthe invention set forth in the applies
tion claims. In neither of the claims of the patent above
considered is "a immovable phonograjjhn blank" an element.
•Applicant states on page I of his specification that he
has constructed removable phonograp blanks in various shapes,
as flat plates with the record formed in a volute line, and as
cylinders with the record describing a spiral line upon their
external surfaces, the latter form being preferred. Supposo
the form first conceived and made to be the phonogram blank
in the form of a flat pjate held removably inthe phonograph
in the manner well understood by those familiar with the art,
and that said form had been illustraDod in this application.
It is clear that a claim similar to claims I and 3 of the ap¬
plication, for example, would be entirely distinct from the
invention covered in the abovepatent; but the invention is
just as independent in reality in the present application,
although the form of apparatus illustrated has the phonograph
cylinder and the cylindrical phonogram blank similar to those
in the patent. At the date of filing of the application
other forms of removable blanks, devised after applicant's
generic invention, were well known.
Claim 4 covers generically the combination of a/phono
gram blank carrier adapted toreeeive& removable blank with
separate recording find’ reproducing instruments. This combi¬
nation is not covered in the patent, although it is there
shown. But since the applications were concurrently pending
this is iirmaterial.
Claim 5 covers generically the combination with a phon¬
ogram blank carrier adapted to receive a removable phonogram
blank, of a reproducer and means for adjusting the reproducer
I lat era3.-3.-y
4
laterally. claims 9 to j2 of the patent embrace certain
specific devices for accomplishing the same object as the
above generic combination, but it is evident that none of
those specific devices, such as the swinging arm, the spectac£
le frame, or the adjusting screws are necessary. Other de¬
vices may readily be substituted, add we > submit that the
application cliams should be allowed to protect the inventior.
in the use of such modifications.
In view of the above considerations we request that the
decisioh of the Examiner,1 in-Chief be revesred.

TO ALL WHOM IT MAY CONCERN :
BE IT KNOWN that I, Thomas A. Edison, a citizen of
the United StatoB, residing at Llewellyn Park in the county
of Essex and Stato of New Jersey have invented a certain now
and useful Improvement in Phonogram Blmks (Case No. 79S) of
which tho following is a specification:
The object of my invention is to produce phonogram
blanks for receiving a record of sound vibrations and re-
produoing tho same by the aid of tho phonograph, which shall
have superior qualitios for tho purpose.
I find that in the composition of such phonogram
blanks it is desirable to use waxes, but that most waxes
when used alone aro too soft for the purpose and it is
therefore requisite to mix-with the wax a harder material. I
find that gum dammar is an especially suituble material for
this purpose though some of tho ullied resins, such as mastic
' y
may also be used.
The wax which 1 prof or to use in combination with
the gum dammar or similar rosin is ooresin and preferably
tho yellow coresin, this being cheaper than white ceresin.But
gum dnmmar may also be used as a hardener for other waxes,
such as beeswax or paraffine.
The mixture which I have found most desirable of the
preferred materials is about 100 pir^S by weight, of guru dam¬
mar to about 88 parts of ooresin.
These materials or such other compound as may be
selected, and as above described, are molted together by heat
and then molded in suitable molds into the form required for
the phonogram blanks, which. aro preferably made in the form

In reply to applic: art's j ett er of March 7,1889
the Examiner states that in view of the decisions of -record, and
the clains presented, that he can see no pounds for a patent as
the case now stands. Appl i oa nt does not. seek protect, ion on a
new composition of matter ,but. upon a phonopram blank. It, is rot
for this Division to pass upon the question as to whether or not
the conpoiation is old or new, since^questians are determined by
another Pr imar y Examiner ,nor does applicant ask it. Furthermore,
such a question has nothing to do with a claim or a phaiopram
blank, which appl i cart make s of any mater ia I (whether old or new)
that he finds suitable for his purpose. In tins case ha has found
that the ingredients of ordinar y varnishes are suitable to his
purpose, and he desires to appropriate the exclusive use of said

Thi9 u » Petition to the fionmii ssion <r praying that
tho primary examiner bo instructed to follow the rvil. irifr s
0? tKo Hoard of Rxaminers- .in- Ghiof.
'H tom as A.Rdison.tho potation or, and tho inyontttr 'of
the phonograph, as is well Joiovn, inscribed his sound record,
in tho first machines produced by Jam, on a shoot of tin
foil. Subsequently in the gradual growth and perfection of
the phonograph, tho use of tin foil was discontinue and
other sound record receivers substituted. In the course of
Mr* F!rlig,jn'q oxporipientg the fact was developed that var¬
ious material s mid conpmuids would be useful as sound record
roc 0 Ivors in the phonograph- those receivers being now known
as phonogram' blanks. .
Other inventors working to improve tho phonograph
or tho gvaphaphon e , w] d oh likewj.se oiplbys a sound record 1
roc diver , and notably Tain tor also osploy-
ed various materials mid compounds as phonogram blanks . '
Some of Rdi son's experiments on phonogram blanks '
developed into applications for letters patent, throe separate
applications having been filed by him .Tuly 3(1,18(18 numbered
1. ■ . •
respectively Mortal Mo 9. 3>»'454, 381457 and the present
application.
Tain tor nl 90 mart® application In ono instance m arc
aware of for letters nitwit/ on a phonogram blank.
Those several njf>p 1:1 cation g come up before the sumo
examiner for action an 4 wove re.i ected on the ground that
thoro was no novelty in using the materials claim®! for a
p honogrom bl auk.
'fainter appealed 'from this action of the Examin or
in hie application above referred to and the Hom'd of Exam¬
iners- in - chief over ml od the Exa:ninor.
With the knowledge of the action of the Ro'drd in ■
Taint or1 e caae.it waa expected by Edison that the Examiner
would abandon his former objection to hi a applications and '
tothat end the Bxwtlner's nttention was called to the Th in¬
ter decision and he was ’requested to reconsider his action
in Edison' s oases.
Whatever reconsideration was had the result was the, '
same, insistence by the Examiner upon the original ground nf
rejection and a refusal to be bound by the decision of tho
Hoard.
Thereupon Edison appealed case Serial Me. 381 457, to
the Board and the Hoard again reversed the Examiner and
Betters Patent No.400b48 wore issued on that amli cation.
Believing that the Examiner would now acquiesce in
the opinion of the Hoard, he was requested to room si dir ids
action in the present case and in case Serial No." 881454.’
The Examiner however again refused to follow the opinion of
the Ho aw! and hence the present petition.
It will be plainly apparent from the foregoing state-
ment that this petition is directed to a determination of
the question whether or not the Primary pjxamin er is bound
to apply the opinion of the Hoard of Rxnminws-in-Oldaf m-jlo
Joiown in one case to an analogous case.
It is a matter of snip rise to us that a judicial
officer in a quasi judicial system such as exi sts in the
Patent Office, should call in question the opinion of an ap-
pell ate tribunal , c ms titu ted and acting directly to cm si. dor
and revise such officers opinions in appealed cases.
'ihe Examiner *s position is plainly that. In Edi son's
case, Serial No. 281404 he says
* Ihe Examiner is aware that he has boon reversed by
the Hxftmin or s-in-i;hi of as stated by applicant, upon a case ’
in which an old composition was used for phonogram blanks,,
but he prefers that if a patent is allowed on this applica¬
tion, .it shall be by the Hoard". • .
Still more plainly is the Examine**' s attitude stated
in t.he argument filed by him in the present caso}
"TJte examiner does not admit that the action of the
Hoard in overruling him in the first binds him for
the second and all similar Cases hereafter".
'Ihis -statement is made ho'-bvi'ihstan<t.tng the rebuke
administered the Examiner by ihe Hoard in rondoring its
opinion in the .Edison case taken up. '(ho Hoard said:
"We iiavo heretofore had occasion to prss upon this
very question in a case coming to us from this sane examin¬
er. Our decision in that case should Jiave settler! the quos-
tiom in all similar cases".

In the matter of the

Thomas A.Edison Petition.
Phonogram Blanks
Serial No. 281,456.
Sir;
You are hereby informed that the decision of the Commis¬
sioner on the above petition is as follows;
"I, do not think this petition should be granted. The remedy pre¬
scribed by law, in case of the adverse decision of an examiner.is
"an appeal to the examiners -in-ohief. In my judgment it would be
"inexpedient to give the general instruction asked by the prayer of
"the petit ion, because it would be of very little service to the
"appl leant, and would be capable of such misconstruction as to
"defeat the purpose intended to be subserved.
"I have detained this oase longer than is usual, with the desire
"and intention of setting forth, so far as I am able, the principles
"which pught to control the relations between the examiners and
"the examiners -in-chief , but I have not been able to formulate my -
currency.
Sh<
“views in such a way as would justify me in giving them
“I think this case should no longer be detained for such purpose.
“ The petition is denidd."

Notary Public
To all whom it may Concsrn, -
Bs it known that I, Thomas A. Edison of Llewellyn
Park, in the Oounty of Essexj in the State of New Jersey,
have invented a certain new and useful Improvement in Pho¬
nogram Cylinders, (Case No. 80S) of which the following is a
specification,
The object of my invention is to produce a phonogram
or phonograph rooord which can be readily and conveniently
transmitted by mail. The main foature of my invention con¬
sists in a cylinder of paper or other flexible material pro¬
vided with a covering of material adapted to bo indented
by the phonograph needle and which can be flattened out or
folded so as to assume a form which can readily be inclosed
in an envelope for WAiling.
In carrying my invention into effect, I first form a
cylinder of paper, and I coat this with the material for re¬
ceiving the record by dipping the cylinder into suoh mat-*.;
ial. For this material I prefer to use mixtures .^f tho salts
of fatty acids, such as oleate of lead and palmitate of mag¬
nesium mixed to the proper consistency and melted. A cylinder
of paper being placed around a suitable metal' cylinder, is
dipped in*o the melted material and such material adheres .
to the surface and coats it evenly and completely.
After the cylinder is thus coated I make, by soraping'
the material, two breaks in its continuity on opposite sides
the cylinder, the material being removed so as to leave
the paper clean on two opposite lines. This enables tho cyl¬
inder to be folded at these two points and such folded cyl¬
inders can be paoked in suitable boxes in the same way that
envelopes are paoked and sold.
When these phonogram cylinders are to be recorded
upon they are taken hold of at the points where they are
creased and drawn out to a cylindrical form again and placed
upon the shell of the phonograph. The paper being flexible
the phonograph oylinder forms it into a cylindrical form
and the message or letter is thon recorded upon the material
on the paper by tho recording needle of the phonograph. Tho
oylinder being then removed from the instrument is folded
again in the same crosses and oan be mailed in an envelope.
To reproduce the message, the paper oylinder is forced upon
the shell of another phonograph and the impressions upon
the cylinder will produoe the desired vibrations of the re¬
producing needle in the ordinary manner. I make the paper
cylinder in a tapering form to adapt it to be placed upon
the tapering shell of the phonegraph.
It is desirable of course that the paper shall not
lap at its edges, since this would produoe an eccentric shape
of the interior of the oylinder. To obviate this, in making
the cylinder I out the paper so that when folded it will be
of the exact size of the phonograph shell with the edges of
the paper meeting and not over-lapping. I then secure the
edges together by moans of a narrow strip of tissue paper
covered with a cementing material 3iioh as hot dextrine
applied very thinly and pasted over the Joint along the
whole length of the cylinder.
My invention is illustrated in the accompanying draw¬
ing:
Figuro 1 is a side elevation ;
Figure «, an end view of the paper cylinder before it
is folded;
Figure a longitudinal section of the same; and
Figure 4 is an end view of a folded phonogram or phono¬
gram blank.
The sheet of paper a is folded into a oylinder and
its meeting edges are united by the strip of tissue paper c.
and then by dipping as already described the cylinder is
covered with the indenting material ,b. The indenting mater¬
ial is then scraped off in a line at d d and the cylinder is
then adapted to be folded as illustrated in figure 3 and to
be drawn up again into cylindrical shape when it is to be
placed in tho phonograph.
Y/h at I claim is!

set forth. ( '

To all Y/hom it may concern:
Bo it Imown that I, Thomas A. Edison, of Llewellyn Park,
in tho County of Essox and Stats of Mow Jersey, have invented
a certain now and useful Improvement in Envelopes for Mailing
Phonograms, (Case No. 80!)}, of which the following is a speci¬
fication.
The object of my invention is to provide an envelope for
enclosing flat phonograms, or collapsible phonogram cylinders
such as aro sot forth in my application filed Beptember 10th
1888, whereby such phonograms shall be securely enclosed and
protected and the danger of injury touthe record from tho
application of dating or cancelling stamps in the post office
or of pressure in affixing the postage stamp, shall be avoided.
In accomplishing this, I make an envelope which has a
pocket or compartment for receiving tho phonogram and an ex¬
tension or flap on which the postage stamp is to be placed
and on which the dating or cancelling stamps are to bo ap- ■
plied. I form this extension or flap by gumming or otherwise
attaching together, the two sides of the envelope for a short
distance at one end, leaving tho rest of the envelope for tho
reception of tho phonogram, the v/holo being covered by the
usual gummod flap.
f'ty invention is illustrated .in tho accompanying drawing:
Eiguro 1 is a face view, and Piguro 8, a top view of an
envelope embodying my invention.
The onvolopo consists of two side sheets a a* and a cover¬
ing flap b, tho edge of v/hich is gummod as usual for scaling
tho envelope. At the .fright hand end, preferably, the two
sides a a* are secured together, preferably by tho applica¬
tion of gum between them, whereby an extension or flap c is
formed which cannot be entered by the phonogram when the same
is inserted in the pocket at the other end, and which furn¬
ishes a convenient place for affixing the postage stamp as
illustrated in figure 1, and for applying the dating stamps
tin the post office.
As is shown in the drawing, instructions may be printed
on tho envelope to apply the stamps only on tho right hand
snd thereof, where there is no danger ofnsueh application in¬
juring the phonogram or the record upon it.
Vhat I claim is:
Thirst: An envoi ope\ for mailing phonograms, having in
combination a pocket or combartment for roceiving tho. phono¬
gram and a flap or oxtensionuor stamping, substantially as
cot forth. \
Second: An envelope for filing phonograms, having
its sides secured together for a portion of its length, sub¬
stantially as set forth. \
Third: An envelope for mailing'Vionograms, having
Lts sides gummod together near one end, sitpotantially as sot
forth.

that the same has not beS^patented to himself, or(jid^diers with ^his^k^vWedge or consent i;
any country ; that the same has not to his knowledge been in public use or on sale in the Unitei
States for more than two years prior to this application, and that he does not know and doe
not believe that the same was ever known or used prior to his invention thereof.
To all whom it may concern:
He it known that I, Thomas A. Edison, of Llewellyn Park,
in tho County of Essex and State of New Jersey, have invented
a certain new and useful Improvement in flothod/^^upTi^ting*
phonograms, (Case No. 80(3), of which the following is a
specification.
Tho object of r,;y invention is to produce a simple and
effective process of duplicating or multiplying tho records
produced by tho phonograph.
The main feature of my invention consists in the employ¬
ment of two points or styles which are joined together so
that the movements of one will be communicated to tho other,
one of which is arranged to bear upon the phonogram to be
duplicated, and the other upon the surface which is to ro-
,, *Tr*' , v-tJfciC Uaa ila-ui- t&rZ/t..
ceive the duplicate record: A These two surfaces being moved P
■ ciAzlL* '
under such pointy, the record produces movements of the point j.
on its surface, which are communicated to tho point resting
on tho other surface and this point forms a record upon the
surfaco under it, which corresponds with tho original phono¬
gram.
-■ prsfe* to employ in this process phonogram blanks made
of a material which when cold, is too hard to be readily in¬
dented by tho recording point, but which may be softened by
heat in order to receive the impressions, and is then allowed
to harden, whereby the impressions aro made permanent.
My invention i3 illustratod in tho accompanying drawing;
Figure 1 illustrated the procona of producing the original
record, and Figure 2, tho process of forming the duplicate
record.
A cylindrical phonogram blank A is placed upon tho cylin¬
der H of a phonograph with the recording point a attached to
tho diaphragm b in contact with its surface. The vibrations
of the diaphragm caused by the sound waves entering I, he mouth,
piece (! are communicated to the recording point and produce
indentations or impressions upon tho phonogram blank as the
sme is revolved beneath said point, in the warmer now well
understood.
When, as is preferable, but not essential, the phonogram
blank is composed of a material which is too hard when cold
to roadily rocoivo tho rocord, but is capable of being soft¬
ened by boat, I employ a lamp D placed underneath the cylinder
whereby tho phonogram blank is kept warm and softened suf£i
ficiently to receive the impressions.
The original record being thus produced, in order to
form a duplicate thereof I make use of the process illustrated
in figure 2. I tako another phonogram blank A' similar to
bb
the original one and support tho two in proximity to each,
ouhor, and so that they may bo revolved simultaneously. I
omploy a reproducing point d and a recording point e, the
former of which bonrs upon tho original phonogram A and tho
latter upon the duplicating phonogram A1. Those two points
ai-o coraioctod together by a centrally pivotod arm 13. \7hon a
material such an above described is omnloyod, a lamp n is
p lac (Hi beneath the cylinder A'. It will bo soon that when
the oylindor/^rovolvod tho indentations of the sound record
on tho cylinder A will givo motion to tho point d and this
motion will through tho am E bo communicated to tho record¬
ing point 0., which will produce corresponding impressions or
indentations upon the phonogram blank A1, whereby a record
will bo produced on said cylindor A', which will bo a dupli-
CL4JC, ZJT
c ate, tin effect, of that bii^oho original phonogram A, and from
which if desired, other copies can bo made in tho some ma;mor .
It is evident that any roquired number of copies can bo made
from one phonogram in this way .
I do not claim in this application the apparatus horoin
described for carryffiglTiy-invention into offoct, sinco this
will form tho subject of a separate applicationT-
What. I claim is:
^\J?irst: Tho method of copying or duplicating a phono¬
gram, wMchxConsists in causing such phonogram to pass undor i
reproducing point, y/hich is connected with a recording point
under which a phonogram! blank is caused to pass at tho some
time, substantially as sevt-orth.
Second: The method of copyiipr.^r duplicating a phono¬
gram which consists in causing such phonogram to pass undor a
roproducing point, actuating a recording poin'b by tho move-
N.
\ mf3nt,s of f>uoh reproducing point, and canning a phono;?' am blank
\o under such recording point, at tho same tine, substan¬

\
Fourth: Tho method of copying or duplicating a phono-
\
i gram, which consists in moving a recording point which acts on
\ M ^ fk jitw/ ^ ujf j-fiPv/a

phonogram, substantially as sotNforth.
Fifth: Tho method of producing duplicate phonograms,

tho record thus formed :
j under a reproducing instrument, the movement «\of which affect
anothor recording instrument acting upon anothor, phonogram
blank, substantially as net forth. \
O ■Sixth:, Tho method of producing duplicate phonograms,
which consists in softening by heat tho material of which a
phonogram blank is composed, passing tho same under tho record¬
ing instrument while in such softened condition, allowing the
same to harden, passing the same under a reproducing instru¬
ment, tho movements of which affect anothor recording instru¬
ment which acts upon another phonogram blank, whose material
is in a softened condition and thon allowing tho duplicate

Dear Sirs:-
With}, reference to your letter of 4th instant in regard
to three applications (Nos'. 733,734 and 806) on certain improve¬
ments in phonographs which were covered by Mr'. Edison's lapsed
English patent No'. 1644 of 1878, and which applications were filed
for the reason, as stated in your letter, that there were some
hopes v. . the Courts would decide that an expired foreign patent
would not limit the life of a subsequent United States patent, I
beg to advise you that Mr. Edison, to whom your letter was forward¬
ed, has now returned it with the following answer to your question
as to whether it is worth while to take out the patents i$ view of
the short time they would have to run:-
"May not the Supreme Court some day reverse all this?
Use your own judgment. Of course I don't want the pa¬
tents for one year only, but if they can be held in office
until Supreme Court decides the case they have before
them, perhaps it might be worth while. Edison’."
I return herewi th the tracings which accompanied your letter now

Sworn to and subscribed before me this . day of ,«s<?
Notary Tablic.
To all whom it may Oonoorn,
Be it known that I, Thomas A. Edison, of Llewellyn
Park, in the County of Essex, and State of Now Jersey, havo
invented a certain now and useful Improvement in Methods of
Making Phonogram Blanks (Case No. 814) , of which the follow¬
ing is a specification:
The object of my invention is to produce cylindrical
phonogram blanks which shall have a perfectly true inner sur¬
face, and which can readily be placed upon and removed from
die cylinder of the phonograph.
The main feature of my invention consists in first
forming a cylindrical body of cord, thread or like material
wound into cylindrical form, and then covering such body
with the wax or other material whioh is to receive the im¬
pressions of tho phonograph. 1' wind the thread or cord
closely upon a cylindrical form or core' and retaining it
upon this form 1 cover it with tho sound recording material
and then remove it from the f orm, whereby a hollow cylinder
is produced, whose inner surface or lining is a closely
wound body of tire material used, whioh evidently must be
entirely true and free from irregularities or eccentricities
of shape. Oonvenient apparatus for carrying my- invention
into effect is illustrated in the accompanying drawing!
Voo
— Figu re is a perspective view of tho machine for winding
tho thri.ad;
Figure a vertical section of the mold for applying !
the sound recording material;
Figure a bottom view,
Figure \ a top view of the cover of the mold.

Referring first to Figure X A is a suitable base
upon which is supported a shaft B carrying a fixed pulley a
e-
and a loose pulley a'. 0 is a cord of tapering cylindrical
form, whose' end D is contracted so that the core muy be hold
upon the shaft B, when it is slipped over the *ond thereof.
Upon a stationary spindle E is placed a spool P containing
the thread or cord 0. A shaft H connected by a bolt I with
the shaft B has upon it a screw thread at K, and upoh such
screw thread a nut b travels. The thread 0 passes through a
hole in a lug on said nut. Power is applied from a suitablo
source by moans of a belt & and it will be seen that when
the machine is set in motion the thread will be wound on the
core 0,and will be fed gradually along the core by the move¬
ment of the nut b. on the scr w thread K so that the thread
is wound olosely along the whole length of the core. When the
thread reaches the end ef the core the projection ,0 on the
nut b, strikes the springs d and Closes the circuit of the
electro-magnet e,, which thereupon by means of the arm f
shifts the belt L on to the loose pulley a' and stops tho
machin e.

posed of 3-n internal backing or lining of closely wound
cord, thread or like material covered with the sound record¬

It is not seen that the .amendment, now made in
this case, affects the claims in anyway, since the method of
winding a strip or ribbon as in Taanters patent,, is t,te same as
the method of winding a filiform material. All cl aims are apain
rejected on the reference of record, and since this rejection does
not involve the consideration of a different question from that
at first considered, applicant may consider this action final and
subject to appeal.

It is thoufjht tliat too claims as now amended will
be found to avoid tho patent to Saint or oltod. Sho winding
of a oord or tliroad on a coro in such a manner as to form a
cylinder with grooved or irregular om’faoc and then covering
this surface with a waxlike material, is not tho same as tho
winding of a flat strip and then winding a second strip over
tho first in such manner ns to form a perfectly smooth and
even surfaoo and then coating too same wito wax. It will bo
observed also that claim 3 spooifios that tho blank is made
by winding a single layer of cord. Shis also differs from
anything shown or described by 'fainter.

| which consists in winding a .cord into a cylinder covered with a
|soft material, th ore by forming a grooved or irregular surface, and
I ’
fin covering the same with a sound recording material. It is
^immaterial to the question of patentability* in this method claim
^whether the finished article is a Graphophone cyclinder or sane
jother cylinder. Hie steps or mode of proceeding alone is all that
|is the. subject of such claim.. Precisely these steps are talten in
finding Elect ro-magne.ts .where the layers wound are covered with an
insulfeting material, as paraffine and another layer is wound on top
of it, thus forming a cylinder of grooved or irregular surface.
Then when finished the top layer is covered with paraffine again,
is a sound recording material. The same mode of proceedure
anticipates all the other claims in this case.
It i:
further objected to the claims presented, since each
step in a method claim must combine with, or mutually depend upon
every other step .like the different parts of a mechanical combina¬
tion, that the step; or feature of forming a grooved cylinder is a
mere aggregation, which in no way combines with the other steps or
contributes to the result accomplished. Hen ce this feature cannot
distinguish these claims from Tainter of record, and it does not
present anything patentable over such patent, it is well recog¬
nized that a mere difference , not influencing or modifying the
action of the real. elements of a claim, cannot be a legal ground
for its allowance. The entire case is again rejocted,and if
applicant so desires he may appeal it from this action.

; TO THE COMMISSIONER OF PATENTS,
sir:
A reference is asked to some
patent or publication which doscribes such a process of wind-
j ing elo otro-magneto as the Examiner believes to be a bar to
|| a patent to applicant for his method of making nhollow oy-
| 1 indr leal phonogram blanks. Applicant is unable to detor-
jj mine from the statement of the Examiner's personal knowledge
of the subject whether he shall or shall not further prosecute
his claim.
Neither is the further obj ect'ion to the claims very
clearly understood. It is certain that the forming of the
cylinder is the most important part of applicant's process,
and we fail to understand why it is said not to-, contribute to
the result accomplished . Re-sonsi derat ion of this point is
asked. _

separator. .1 prefer to uso a magnetic separator of the class
set forth in my patent No dated
in which the mingled magnetic and non-magnetio materials aro
allowed to fall past the poles of tho magnet whereby the di¬
rection of falling of the magnetiopar tides is altered and
such particles fall into one receptacle, while tho nonrmag-
nutic particles fall in a straight lino into another reoepto-
olo. By this means the iron particles aro effectively and
quickly separated from the other portions of the ore.
A (3 above stated the ore nood be hoatod to a xkocX rod
heat only if the heating is done in an atmosphere of a re¬
ducing agent. To accomplish this I mix the pulverized ore
with a small quantity of charcoal or other carboh and heat
tho same in a chamber to which the air has only slight uc-
coas. This air combines with tils carbon to form a carbon
monoxide and tliis reduces tho surfaces of the iroh particles
to magne tic oxide and enables them to be used in the magnetic
separator.
What I claim is:
'flic pruees^ of separating non-mngnetie iron from its
ore, which consistsXin pu.lvori z ing the ore, posting the samo
so as to make the iron magnetic and then separating the iron
from the gongue by magnetic at trac tion, subs tantially as set
forth.
The method of separating non-magnetio iron from it3

To the Coirmissioner of Patents:
Sir:-
PleaBe insert the following claims:
The process of separates non-inagnetio iron from its ore
which oonsists in pulverizing the ore, heating the pulverized
ore approximately to ,* white HOat, allowing the ore to cool,
and then magnetically separating the iron from th , gangue.sub
stantially as described. '
The process of separating non-rnagnetic iron ifrom its ore
Which consists in pulverizing the ore and mixing it with a
quantity of carbon, heating the mixture whereby the iron is
rendered ...agnetio, and then magne tioall y separating the iron
from the ganguo, substantially as described.
Change original claim 2 to 3. The Smith patent cited
discloses a, different process from that defined in the claims
in this application, as also does the machine illustrated in
th e American Institute of Mining Engineers, vol/ 9, although
both resemble the present invention in certain particulars.
The two claims which have been added bring out a little more
in detail the several steps of the prooess.
A favorable reconsideration of the application as amended
is requested.
Respectfully,

To all whom it may Conoorh,
Be it known, that I, Thomas A, Edison, of Llewellyn
Park, in tho County of FSssex, and State of Mow Jeraoy, havo
invented a certain hew and useful Improvement in Methods of
Coating Objects with Liquid Matenfajf, ■3SX tho following
is a specification:
Heretofore the processes employed for covering arti¬
cles such as furniture and household utensils with liquid
material, such as varnish or Japan, havo been laborious and
difficult when an even and smooth surfaoe coating was re¬
quired. Hie objeot of my invention is to enable such arti¬
cles and any articles to be covered with even coatings of
varnish or like material in a very simple and effective
manner .
I have found that if the objeot to bo coated is re¬
volved in two or more directions simultaneously, tho liquid
placed thereon will be caused to flow ewenly through all
parts of tho object and will produce a perfectly even ooatiig
upon every part. I havo dovisod apparatus for performing
this operation, which however I do not olaira in this appli¬
cation, confining myself heroin to the method of operation
or- such apparatus.
The apparatus referred to is illustratdji in the ac¬
companying drawing:
F.igurte 1 is a side elevation, and
Figure a, an end view thereof.
A is a shaft supported in bearings on standards B B
and projecting beyond the standard at one end. Such standards
are supported by a suitable base 0, and shaft A carries out-
. . . ' 1.
side of its bearing a suitable frame I), which is shown as
consisting of a baok piece and two outwardly extending arms
E. Through the upper one of the arms E passes a shaft F,
which carries a wheel fi.
As shown, the objeot to be coated, is a tapering
cylinder H, such as is used as the core in forming tapering
cylinders for use in the phonograph, such core being covered
with wax or wax-liko material which is applied in a softened
condition find allowed to harden. This is shown as supported
on a spindle extending between the arms EE, but whore ob¬
jects of different form are used with the machine they may
be olamped or supported between such arms in any suitablo
way .
The wheel (} makes a frictional oontaot with the sur¬
face of a large disk I. Power is applied to the shaft A by
means of the pulley K and it will bo soon thut the cylinder
II or other object which may be substituted therofof ,wlll
thus be revolved bodily on, a transverse axis, while at the
seme time the wheel 0 and shaft F are turned by the friction¬
al oontaot of said wheel and the disk I, and the cylinder H
is therefore revolved also on its longitudinal axis. The
molded wax or other liquid material being applied to the
oylinder H and the same being turned in the manner Just do-
scribed, such material becomes spread evenly ovor ev<ry por¬
tion of the cylinder and forms a corripleto and even coating
thereon. Tho samo will bo the case with any object which
may be substituted for the cylinder H, such as a chair or
other article of furniture, or a cooking or other utensil.
In order thut objects of larger size may bo substi¬
tuted in the Machine, I make the wheel 0 removable by the
withdrawal of the sorow at a and I also arrange the disk
I so that by loosening tho thumb nut I. the said disk may bo
slid back on tlio base, whereby a larger wheel may be substitu¬
ted at f} and sufficient spaoe is provided for an article
which is larger thah or of different form from tile cylinder
What I claim is :
1. The method of coating a body with liquid material
which consists in applying such material to the body and
moving said body simultaneously in two or more directions,
substantially as set forth'.
SB, The method- of coating a body with liquid material
, ■ _ "fc. 4 (4- 6
which consists, in applying su oh material to -stfeh-^obd cot, and
simultaneously revolving such body in two or more divergent

Department of tee Interior,
The Examiner holds that the claims in this case do not in¬
volve a patentable process. They seem to relate to the mere func¬
tion of the machine and actually cover the compound motion produced
thereby. Attention is called to the patents to

Tlw patents to which attention has been called as wo

feeding it to the paint brush. A man advancing nn article
to a stationary paint brush and twirling it in his fingers
v/oulf pairTonn precisely the same motions as Baldwin performs.
ijorbra'cht ’employs a Bimple rotary motion to throw off the
. surplus, paint. -
Harlan by the reciprocation of a dasher causes "paddlbS"
to revolve — this in a churn. IVe presume this latter rpfdr-
enco; waif. cited to show that a canpotmd motion was old.
does not seen' to us that, any part in Harlan's device is sub--
j ected to a compound movement.' ' ,
As far as the references show the compound movement em¬
ployed by applicant is now - but we do not base applicant's
right to a patent on the ground of the novelty of that move*
meat. Bo the movomont new or old, the invention still Vi* '
mains tho same residing in the discovery that such compound^
mo.vem.ont when enployed as a step in a process would offect'aF
2
new and useful result.
Applicant's process cones within the definition of a
process laid down by the authorities. Coming; vs burden 15
■hoWI/P 253, a leading; Supreme Court Case on process patents.:
says "A nev; process is usually the result of a discovery*
• What. is. not a process is defined in that case by referring; to
the process of planing a board, of grinding grain, of hranmer-
ing .iron, etevy ft’ which it is said: "In this use of the
term p roc egg it represents the function of a machine or the
effect produced 'on the material., subjected to the action of
the machine. " ■ ■
Nov; applicant1 s process is the result of a discovery,
; nnd it not the function of a machine, nor is the function of
ft machine claimed. Closely analogous to applicant's case
*ls that 'of Me. Clung vs Kingsland, 1 How. p 202. Commenting
fiipoP. this case Mr. Walker in his work on patents' ’.(2nd edition
section 8) says: • *1^ appears that some metliod was long sought
by moanp o' f which- WoHers -or Cylinders could be^enst that; 'the.
mo tnl ,■ -when introduced into the moulds, would bo given •
rotary - motion, to the end of throwing the flog or dross iwtOt •
the centre instead of the circimferonce of the casting.: ' Thft
fact that rotary motion v;ould so result wan an understood ’’- t
law of nature,' an understood operation of centrifugal foroev
Hie probl an was' to' produce such a motion more conveniently ,.
and more uniformly than try 'stirring 'the liquid metal with a
circular movement of ;an implement inserted therein. That •
problem was solved in 1884 by James Harley, a workman in"a ’.
’ foundry in Pittsburgh, Pennsylvania. He discovered thatwthor
I'ntwy motion .dosired.cpvild bo • iispnrtod to mol tod mortal by
footing that, metal into a mould diagonally instead of
perpendicularly or horizontally. a patent was granted to him
"in 1835, for "an improvement in the mode of casting chilled
rollers and other metallic cylinders and cones*. litigation
arose on the patent, and coning bofore the Supreme rjourt it
was held tq bo a patent for a process,*
; 'Ih that -case it was discovered that a rotary motion, the
effects of which wore loiown,' could he pm di teed by a particular
method. Here it has- 'been discovered that a' canpound move¬
ment, whether before known or not will produce a new effect
when omployod as a step in a process. •
In neitlwr case was or is the machinery used of the "
essence of the invention. Any machinery employing the •
method of the patentfldn «c.Clurg vs Kingsland might well be : '
. hold an infringement, here any machinery or mechanics why
be used to effect that step of the process, involving the
■ use of. the compound movement..' •,-V '
In ex parte Merr 41 n.n. 403, n. process is \voll ’defined
’in the following language: »a method or process such aft the
law recognises as patentable must have an existence in depend-^
•ont of the machine or apparatus by w)d. oh it is carried mitft»
its result. It must be a method or process that can bw.-
carried out hand or by various kinds or forms of nrtdhhnisra
or apparatus. If the act or msult is sirnply that o? the
mechanism. itsjfd-f, so related to it; that 'it cannot exist in-
dep endontly and it is the solo utterance of the machine then-
tile supposed method or process does not exist," -'V-hMi**

,,n tfach claim of the present application involves two steps
the first in each olajtm being the application of tho liquid
. material to the body being treated. This stop may bo per-
-.0r,'rl0,ri. any suitable mechanism or by hand.
• • ' : ■■ The second stop involves the subjection of the article ■
• at tor tJw coating material has boon applied to it, to a'
"simultaneous movement in two directions. .Any suitable
"mechanism may perfom t)ds movement and it may possibly be
performed by hand. .
It seoms to us tJiat the only logical conclusion follow-
ing fron a consideration- of applicant’ s invention in connoc-
•.tioif.wlth 'the authorities is that it is a process in the true
v'sonse of that term and that it is properly claimed.
Applicant 1b the first discoverer of the fact that a
ccmpoiuyl motion imparted to a coated object at a certain " 1
stage, of sc process will effect an equal distribution of the ' ;
coding. , llLi's- was his invention. Had he stored here 'his
process invention remain couplets,' But he wont further

cess 4d vilsclo sed and gave the public the benefit of sifch -1

TO ALL WHOM IT MAY GONCURH:
BB IT KNOWN, THAT I, THOMAS B. BDISOIT, a citizen
of the United States, residing at Llewellyn Park in the
County of Lee ox and State of How Jersey have invented a
certain new and useful Improvement in Phono^aplis^of Swhxch
the fallowing is a Specification:
The object I have in view is to improve the cutting
or turning off tool of my Phonograph so that it will better
retain its cutting edge and will produce a smoother and
I have found that in order to produco the fine and
■perfect surface necessary for the perfect operation of the
Phonograph, a steel turning off tool cannot be depended
upon to retain its cutting edge, and I have also feuna that
if a cutting knife is employed having the ordinary cutting
edge, i. o., ono forming an acute angle that a rough sur¬
face will be produced in turning since the edgo of the knife
enters under the surface of the mat orial and breaks it up
into chips 'which in breaking away from the surface carry
with them a portion of the material below the line of •
cutting and thus produce a rough surface. For my improved
knifo I employ a j owel such as sapphire since I have found
that sapp=hiro will hold its cutting edge effectively, and
I grind the cutting edge to form a right angle or approxiw
mately a right angle so that the edge will not enter be-

_ - Vi .we is a top view of the spectacle frame of
my Phonograph showing tho turning off tool or knife mounted
thereon;

A, is tlie spectacle frame of my- Phonograph carry¬
ing in its oye, a, the recorder which is not shov/n.
To the under side of the spectacle frame is rigidly
secured tho turning off tool, T„ My improved tool has its
point ,. b, .formed of a sapphire or other suitably- hard jewel
ground to shape and secured by a clamping plate, c. I
have found that the sapphire holds its cutting edge and
produces an exceedingly fine smooth surface. Tho turning
UK
off tool is supported as shown in figure S, so as to pro-
sont its cutting edge obliquely to the surface of the pho-
n0-ram blaMk* Th“ °wm ocLvo, c, is around to form a
right angle or approximately a right angle instead of an
aouto angle as has been heretofore employed by m. The
bnife, C, having it shutting edge forming an acute angle
as shown in f i --jure ^ enters beneath the surface of the
jmaterial. in turning off the blank and as the chips break
away fro* the surface they carry with them a portion of the
material below the lino of cutting as shown by the dotted
line in figure But where an edge forming a right
angle, or approximately a ri.*t angle is used, the point
of the tool as shown on figure ^above t$e cutting edge
breaks this material away as fast as it ia cat and t he rG
suit is that the chips break close to the edge of the tool
and do not carry with them any material below the lino of

jewel cutting edge substantially ns sot forth.
% In a Phonograph, a turning off t col having a
jewel point secured by a clamp to the stock of the too^,
substantially as sot forth.

off tools shown in the above patents also anticipates the claim.
Claim 4 is rgj ected on the ordinary turning oif tools used in
turning brass ,w hi ch tools have right angled edges. An example of
such tools is described on page 521 "Holtzapf fels Turning and
mechanical Manipulation* Vol . II Holtzapftfel and Co., London, 1847.
Claim 5 is rejected on the same ref erence.and the ground is further
taken that a jewel cutting tool i s not patentable over the same
tool made of steel.

_ The object of my Invention is to provide means
uso an^ft^giv^^ovrol like sapphire without materially
increasing the cost, of the machine. This I accomplish b.y
taking small and irregularly shapo A sapphires which v/ould
fit the cup
the ena of
the steel pin and by setting such sapphires into the oup of
the Stool Stop by imbedding them in a suitable cement
placed in such cup, such as oxy-chloriuc of sine or mag¬
nesium, taking care that the jewel projects at the center
of the cup above the edges of the cup. After tho cement
has thoroughly set so that the jewel is hold firmly in
Piece, tho jewel is hold against a suitable grinding im¬
plement and its face ground off so as to leave a smooth
surface at the center of the cup. ' The shaft of tho motor
being held against lateral notion by a suitable bushing
and being pointed at its cud, it rests only upon the center
of the j oi7c 1 or approximately upon its center', so that so
long as the jewel is ground smooth at tho center of the
cup it. becomes immaterial whether it fills tho rest of tin
cup or whether tho rest of its surface is smooth or irreg¬
ular. In this way sn exceedingly cheap construction is
produced employing cheep sizes and forms of the jewel and
requiring very little manipulation in grinding.

form the stop, the upper ond of the steel pin, d, is bored
out to form a cup into which I have heretofore fitted a
jewel which has been accurately ground to conform to the
shape and sizo of the cup. In using an expensive jewel,
however, like sapphire which T now employ, I have found
that that method of mounting tho jewel upon the stool pin,
is exceedingly expensive. I therefore take a smaller and
cheaper jewel, ^ which is placed in the cup in the upper
end of tho pin, d, and is cemented therein by any suitable
cement such as oxy-chloride of zinc or magnesium and is al-

This case has been reconsidered in connection with the
argumait of counsel.
The claims are finally rejected as involving no invention in
view of the references cited. While it is doubtless true that ex¬
pense would be avoided by using an undressed or rough jewel in¬
stead of ajgibund jewel, such use would appear to be more of a ret¬
rograde step than an advance in the art, and any way, as already
intimated, involves no shadow of invaittpn.

Please find, below a communication from the EXAMINER in charge of the application
This case as last amended has been considered.
All the claims are again rejected as involving no invention
over the references cited, and the 3rd also because to an ille¬
gitimate combination. The patents given shown every feature em- ■
bodied in the claims except the "rough" jewel. In them are shown
a shaft, a step or bearing therefor having a cavity in its end, a
jewel, and cement or binding material to hold the jewel in place.
As previously stated all j ewel -settings are provided with pro¬
jections of seme form din order that they maybe securely held in
position. Furthermore, anciently it was customary to set pre¬
cious stones in their rough or uncut condition. This statement is
to be found in C. W. King's "Antique Jems and Rings", Vol ./, p.37,
published in 1872 in London, by Bell & Daldy, which work may be -
found in the Patent Of fice„;Librar.v^„._The f ollowine i s a Quotation

„ "The most valuable stones, as rude as when just picked up,

Appeal to the Board may be taken now if so desired.

To all whom it may finncorn,
** •'mown that I, Thomas A. Alison, a citizen of

of Rssex.and State of Mow Jorsoy, have invented a certain
now and useful Improvement in R1 on trip ibtors for Phono- •
graphs ( Oaso Mo. 841) of which tho following is a specific
cation:
In 'the phonograph whon the same is operated by an'
electric Motor .1’ H'nVo heretofore provided the motor with a
plug switch for making and breaking its circuit, in starting
and 'st typing the mao) lino. Such a device is not found aiti po¬
ly satisfactory partly because of the inconvenience of a
plug switch and also because when the plug is withdrawn to
stop the machine, it does not slop instantly but continues '
to run until- its momentum is, overcome,:. f;,8 o-moct oi' mv

brake ■which when the switch is moved to open the circuit is
brought into contact with a pulley intermediate between th'o"
motor and the phonograph or with any other convenient, part,
whereby the machine is stopped immediately on tho circuit '
of tho meter being broken*
My invent Ion "is illustrated in the aece^, eying

CERTIFICATE F1LED IN N, V. C(
To all whom it may Concern, -
Be it known that I, Thomas A. Edison, a citizen of
the United States, residing at Llewellyn Park, in the County
of Essex and State of New Jersey, have invented a certain
nevf and useful Improvanent in Phonographs (Case No. )
of which the following is a specification:
My invention relates to certain iniprovenents in
the phonograph designed to make the same more convenient
in use. As is now well understood I employ in the phono¬
graph a tilting bar extending past the front of the phono¬
gram cylinder by turning which the traveler atm and specta¬
cle frame are raised together off the cylinder to enable
the attracting movement to be given to that. I have hereto¬
fore employed for the puipose of moving the tilting arm_,ei-
ther a thumb screw on a spindle connected with the aim
or a treadle to be worked by the foot of the op erator. These
arrangements have in some cases been found inconvenient and
the special object of my present invention is to provide a
device for the purpose which shall be more simple and con¬
venient in its operation. To this end my invention mainly
consists in providing a tilting bar with a handle placed
at a convenient point for moving said tilting bar. Such a
handle may be situated and arranged in several different
ways, sane of which are shown in the accompanying drawing
in which,
Figure 1 is a front elevation of the phonograph pro¬
vided- with my invention, and
Figure 2 is a cross section on the line 2, 2 of Figire
1 showing another arrangement of the operating handle.
}
A is the phonogram cylinder, B the phonogram blank
thereon, C the spectacle frame carrying the recorder and
reproducer, D the feed screw, E the tilting bar and a the
presser foot. AttacheZd to the lower side of the tilting
bar E is a fork F and within this fork is a cam b (See
Figure 2) and by the turning of this cam the tilting bar
is raised and lowered.
In Figure 1 the cam has attached to it a spindle
c which may if desired have upon it the thumb nut d. Around
the spindle is twisted a cord G.the ends of which are at¬
tached on both sides of the fulcrum of a lever H which is
provided at each end with a thumb piece e. A spring f is
interpolated in the cord. G for keeping tension on the core.
By pressing down on one end of the lever H the tilting bar
is raised to raise the spindle frame slightly by turning the
cam e and by pressing the other end of the lever the tilting
bar is lowered again.
In the form shorn in Figure 2 the spindle c of the
cam b has attached directly to it a handle I and by raising
or depressing this handle the tilting bar is raised or low¬
ered by the turning of the cam.
What I claim is:
1. In a phonograph, the conbination with the tilting
bar in front of the cylinder, of a handle connected therewith
for turning the same, substantially as set forth.
2. In a phonograph, the conbination with the tilting bar
in front of the cylinder, of a spindle connected therewith
and a handle attached to said spindle for turning the same
to moye said bar, substantially as set forth.
■ 3. In a phonograph, the conbination with the tilting
bar in front of the phonogram cylinder, of . a cord attached
•V.
thereto and a lever pivoted on the'base of the machine
connected with said cord for turning said spindle .substan¬
tially as set forth.
4. In a phonograph, the combination with the tilting
bar in front of the cylinder.of the spindle connected there¬
with, the cord on said spindle, a pivoted lever attached to
said cord and a tension spring in said cord, substantially
as set forth.
5. In a phonograph, the combination with the tilting
bar in front of the cylinder.of the can "and. snindle ,and
a handle connected with said spindle, substantially as set
forth.
6. In a phonograph ,the combination with the tilting
bar in front of the cylinder.of the cord connected with
said bar and the lever pivoted on the base of the machine
and connected with said co id, substantially as set forth.

I To all whom it may Concern,
Ho it known that I, Thomas A. Brtison, a citizen of
+'ho States, real dint: at Llewellyn Park, in the Coun¬
ty of Rea ex, and State of New Jersey, have invented a certain
now f«id useful Improvement in the Process of Magnetic Repa¬
ration (Case No. ) of which the following is a spoci-
TJw) object of my invention is to provj.de for the ef¬
fective separation of magnetic" iron ores and move especially
to accompli eh such separation in the case of what are coll od
“lean" ores, that is those in which the proportion of iron 7
is very small,
Oros in which the proportion of iron is loss than . . ,
about thirty per cent have never, before my invention, boon '
economically worked even by m ordinary process of magnetic
separation because in tho crushed ore there are many parw
tides which. are composed partly of iron and partly of
non mannetio material and these are either drawn anong the
iron particles and diminish the purity of the product,, or if
by weakening the magnet it is attempted to avoid this, the
loss of iron in ths tailings is too great. It will be seen
that in tho lean ores there is a greater proportion of iron
particles which are in emtaet with non-magnotic particles,,
than in richer ores in which many iron particles are ih con-
tact with one another, and this is the reason why, in crush¬
ing, so m^v, composite particles made up partly of iron and
partly of non- magnetic material or gangue are foimed.

The fractional separation of metals from their gangue, and of
lighter from heavier oils is well known. ' Aside from the use of
successively stronger magnets, there is .not even the merit of. frac¬
tional separation; properly speaking, in applicant's device^ but
merely doing to poorer ore what has already been done to richer
ore, originally associated with it. ' This use of successively
stronger magnets, however, is old, as shown by patent to Conkling,
#401,414 April 13,1889, There is nothing patentable in treating
the products of Conkling’s process.

SIR:-.
U *9m* iy) «8 that this application embodies
something mors than an ordinary process of fractional, sepa¬
ration or than such a process as that of Conkling, cited.
_ - -/Applicant's object is to obtain as a product
from loan oroo pure iron in paying quantities. The Conkling
process will not accomplish this. Conkling will obtain a
small quantity of pure iron, and larger quantities of iron ;
mixed with more or loss gangue.He will thus either lose a -
large amount of iron in the tattings or his product will bo
impure, except a fractional part- of it. Now applicant gets all
the iron out and gets it in a pure state, and does this by
the definite steps of separation which he claims. The making
of a definite division between the pure iron parti ol os 'and
the composite particles, is original with an>lJ.cant;so is'tto
subsequent separation of those composite particles from’ Ih'd;
>ure ganguej and then is the especially essential step,
* '0thlne in my way Mtioema to which is found in Conkling,
‘ )f disassociating and final If *?>a.mting the component parts
)f the composite particles. Here is a well considered proc-
3so each step of which is new ty itself and certainly the
sequence of such steps ought to be patentable. A process
like, Conkling has just the result which applicant seeks to
[7/29/89 E 845 S.N. 319,401 Magnetic Separation]
avoid. It cannot obtain from a loan ore, a paying quantity
o? pun iron. It might bo useful with rich ores.whore the
Wiioto in the tailings nood not be con si derod; or it might bo

Office;
On reconsideration of this case no patentable process is seen
over Conkling's of record. Conkling's first step is exactly that
of applicant-viz: -separation of first crushed ore into finer and
coarser grades. It would be absurd to prevent Conkling from re-
orushing and reseparating the coaser products of his first opera¬
tion.
The claims are finally rejected.

It will be seen that these claims are merely for the applica¬
tion cf the well known methods of fractional separation employed in
many arts. All applicant has done is to apply the old magnetic
methods over and over again upon his ore, empl oying successively
stronger magnetic fields, as the ore becomes poorer. The 'claims
of such a process to the protection of the patent laws would be but
slight even were no references to be found touching upon it.
But such a reference has been found in patent to Gurdon Condoling
#401,414, April 16th, 1889.
This patent expressly states (beginning line 69) that the mag¬
nets are so graduated that the pure iron particles are first sepa¬
rated, and that then successively less pure strains of ore are
drawn out of the mass, as it passes unde^successive magnets. The
magnetic fields are made successively stronger either by closer ^
approximation of the poles to r.he ore, or by the use of stronger
m^rnets .
The universal method of separating magnet ic iron from its sur¬
rounding gangue is by crushing the ore, and subjecting the crushed
mass to the action of magnets. If this process is so well known,
as applied to ore directly fron the mine, can it be argued that it
is novel as applied to ore previously thinned by the process of
Gurdon Conkling? In the opinion of the Examines applicant has
not only shown no invention in so doing, but he has only done what
it may with perfect fairness be inferred that Conkling does with
the products of his process.

PILED AUGUST 1, 1889
IN APPEAL TO
BOARD OP EXAMINERS-IN-OHIE?
MEMORANDUM OP ARGUMENT FOR APPLICANT.
The four claimB in the above ontitlod application
e :• A
wore rejected by the -Examitroir- for want of patentability in
view of patent to Oonkling No. 401,414, April 16, 1889.
The object of applicant's invention is, to obtain
the iron from a low grade or loan magnetic ore in a
practically pure condition.
Briefly stated, applicant's invention consists in
crushing a magnetic ore (or in taking a pulverized ore)
and subjecting the fine ore to a magnetio attraction strong
enough to remove all of tho pure iron particles (or
particles of iron oxide) but not strong enough to remove !
particles of iron which are associated with non-magnetic
gangue. The tailings, whioh oontain all of the gangue and
the combined particles of iron and gangue, arc then subjected
to a magnetic attraction strong enough to separato all the
particles whioh oontain, or to whioh are connected, iron in
any appreciable quantity. . At this stage of the prooessHho
entire mass of ore is divided into throe parts, (1) pure’
iron, (8) iron associated with gangue, and (3) gangue con¬
taining; no iron. The next step in applieant'B process is.
to take that portion of tho ore containing iron and gangue
and crush it by rollers or otherwise to mechanically die—
[7/29/89 E 845
>.N. 319,401 Magnetic Separation]
aoeiato the iron partiolcs from the gangue, and then to
aagnetioally separate- the iron from the gangue. The third
|i part above indicated, containing no iron, may be thrown
aside as worthless* and need not be rehandled or again passed
Hjfwv t£L <u
magnetic separator*
This is a very economical process of separation for
poor ores, and one by which a nearly pure oxide of iron
product is obtained and practically no loss of iron takes
place in the tailings, + ^ .
ft ftC-’-.t- .
The ConKling patent describes a process and ap¬
paratus by which crushed ore is separated into (1) iron
particles, (2) iron particles associated with a small
| amount of gangue, (3) iron particles associated with a
larger amount of gangue, and so on suocessively, and,
finally, pure gangue. This separation is effect od magnoti-
eally as in applicant’s proeesS/G^fU L.. ffLrvva o-
There is nothing in the patent to show what is done
with the material thus separated into piles of different
grades. It is not suggested that the material containing ‘ j
iron and gangue la rcoruahed and the iron particles separated
magnetically. If, in fact. Conk ling recruBhes such ma¬
terial (which we do not admit) it is clear that he jjgyld^
not simultaneously reorush all of the tailings and separate
the iron partlales from all by one operation, for in that
case separation of the ore into suooessive grades would be
useless.
At no time in Conkling’s praoesB as oarried out by
the apparatus illustrated, is the ore separated into three
parts as above indicated in connection with applicant’s
[7/29/89 E 845 S.N. 319,401 Magnetic Separation]
- 3 -
proooos, hence he does not and cannot perform said process.
While in applicant's process the pure gangue is separated
from the iron and magnetic sangue- by the second step of the
operation, this is not aooompliohed in the Conkling process
until the third step, that is, until it haa been subjected
to the third magnetic separation. The ganguo, therefore,
unnecessarily adds to the bulk and weight of materia! passed
through the final magnetic separator (w at the right in
figure 3 of Conkling' s patent), and by covering and impeding
free motion of the magnetic particles makes a stronger
separator neocssary.
It has already been indicated that the Conkling •
patent does not indicate what is done with the separated ore
of several grades. As is well known, it is ouBtomary in •
dealing with iron ores to transport them, after separating- -
as much of the worthless ganguo as oan easily be done mag¬
netically (as in Conkling's process) or otherwise, to a
proper furnace or plant, and there reduce them to the form
of pig iron or other form as desired. It iB probable that
the magnetic ore obtained by Conkling is designed to be
taken from the separator to proper furnaces as above in¬
dicated- If this is so, the purpose of the separation into
successive grades is clear, viz., so that eaoh grade may bo
properly treated, that is, may be exposed to a proper tem¬
perature in the furnaoe, may be kept in the furnace a
proper length of time, etc. further , if the above sup¬
position is correct, in (ionkling's process a large amount of
worthless gangue would havo to bo transported from the

S.N. 319,401 Magnetic Separation]
s-oparator to the furnace with^^eaeh^grades of ifea-aiparatad

; ported,u_ana this is a vory important saving, a^^^ygiTqpe
| i^o^e^iif'l^o^liti^^^o ^transportation is difficult and
costly.
A3 the result of applicant's process, all the iron
in the ore is obtained by new and simple treatment in one
high grade product of comparatively small weight and mass,
and which can all be treated at once in ft reducing furnaoe,
while as the result, of Conkling's process all the iron in
Jthe ore raay^ be obtained, but is distributed through several
products of different grades, of great weight and bulk, and
which require separate treatment in the reducing furnace . ...

ON APPEAL TO THE
COMMISSIONER OP PATENTS PRO:

MEMORANDUM OP ARGUMENT POR APPLICANT.
Tho four claims in the above entitled application wer
rejected by the Board for wont of patentability in viovr of
| patont to Conkling Now 401,414, April 1G, 1889.'
The object of applicant's invention is, to obtain pur
| iron from a lor; grade or loan magnetic oro without having any
m-magnetic material mixed with the product and without
| losing any iron in the tailings.
Briefly stated, applicant's invention consists in sub’
jocting crushed or pulverized magnetic iron ore to a magnetic
attraction of a determined strength sufficient to remove from
the mixed mass all of the partioloo which are composed solely
of iron, but not strong onough to remove any composite par¬
ticles made up partly of iron and partly of non-magnotic
gangue. The tailings, which now consist of all the particlos
of puro ganguo mixed with all the composite particles of iron
and gangue, are then, ao the next stop of tho proooBS, sub¬
jected to a magnetic attraction strong enough to separate all
| the particles which contain, or to which are connected, iron
in any appreciable quantity fran the purely non-magnotic par¬
ticles or ganguo. At this stage of tho process the entire
mass of oro has bocomo divided into throe parts: (3,) all
puro iron, (2) all composite particles of iron associated
[7/29/89 E 845
S.N. 319,401 Magnetic Separation]
j '.tfith ganguo, and (3) all pure ganguo. The next stop ia, to
! take tho composite portion of the ore and crush it by rollers
or otherwise so as to mechanically disassociate tho iron pc-tr-
| tides from tho non-magnet i a particles, after which, by moans
of a third magnetic separation, the iron is separated from its
i disassociated ganguo. Tho third portion, which contains no
| iron, may be thrown aside as worthless.
This is a very oco.nomical process of separation for
! poor ores, and one by which a pure iron product is obtained
and no loss of iron tokos place in the tailings, and no ganguo
is loft with the iron to bo rehandled and to complicate subso-
! <*uent reduction of the ore. Tho product is one which by rea-
; aon 0:C tho absence of phosphorous and other impurities is
! ®*apted perfectly for use in the Bossomor process of malting
stool .
; The Conic ling patent describes a prooess and apparatus
by which crushed ore is merely separated into several grades,
that is, one of substantially pure iron particles, another of
iron particles associated with a small amount of gangue, an-
otlier of iron particles associated with a larger amount of
gangue, and so on successively . This separation is effected
magnotioally as in applicant's process, although by a dif¬
ferent apparatus .
At no timo in Conkling's pi’oeoss as carried out by tho
apparatus illustrated, is the ore separated into throe ports
as above indicated in connection with applicant's procoss,
hence ho does not and cannot perform said process. In Conic-
ling's process tho built of tho gangue i3 carried through all
of tho separators and therefore not only adds to the bulk and
[7/29/89 E 845
S.N. 319,401 Magnetic Separation]
wiCht material passed through the final magnetic separator
| (I'1 at the right in figure 3 of Conkline's patent), but by
covering and impedinc free motion of the magnetic particles
I mol.es it impossible to completely remove tho latter, so that
many particles of iron mat bo carried into tho rofuso tail¬
ings and lost. With applicant, on the other hand, tho bulk
of the ganguo is removed in the first stops of the process, so
that at the end the separation of the iron particles is unira-
; peded and comploto.
As the result of applicant's process, all the iron in
I the oro is obtained by this simple treatment in ono high grade
product of comparatively small v, -eight and mass, and which can
I a11 be troatod at onco in a reducing furnace, whilo as tho re¬
sult of Conkling' 3 process tho iron obtained will bo distri¬
buted through several products of different grades, which are
difficult of transportation to the furnaco because their weight
i and bulk al"G ™ade larnc by the worthless "ganguo combined with
tho iron and which require separate treatment in the reducing
furnaoe.
To comparo tho process of Conkling with that of Edison
more roadily wo have shown them side by side in tho qc company -
ing sketch. Tho sketch shows that by Conkling' s process the
iron obtained would bo divided into several piles of different
grades, markod "I-’irst product", “Socond product" and "Third
product" on the sketch; it shows also the entire amount of
gangue passing the last separator bolt . On tho other hand,
the sketch shows that in the Edison process the iron'*' obtained
i3 all of ono grade, pure iron, and that the lar-gor part of
the ganguo is entirely out of the field of the last separator
[7/29/89 E 845
S.N. 3X9,401 Magnetic Separation]
magnet , *
'i'he Examiners in Chief say "the Examiner holds that no
invent ion would bo involved in tho rogrinding of any of the so
imimro products (of ConklingJ to got a product of greater
purity by a second operation", and they soom to concur in this
opinion. This P'nraso scorns to us to show a misapprehension
of what the process of applicant really consists in, bocause
oven if Conk line described tho recrushing and reseparating of
any one of his products ho would not do wlmt applicant does
and would not practice the same process, and especially ns do-
fined in claims 2, 3 and 4, for no one of Conkling’s products
is tho mass of all composite particles which is what applicant
rocrusheo and separates, after making a definite separation of
it both from pure iron and from pure gangue.
Y/o must deny the vague and general statement in the
first sentenco following the claims in tho Examiner' a state¬
ment. Tho claims are not "merely for the application of tho
well known methods of fractional separation employed in many
arts", whatever that may mean, as stated by tho Primary Ex¬
aminer. Tho claims involve the separation of tho iron in a
particular way, and a dofinlto treatment after preliminary
separation (as already indicated in tho description of the
proooss), which is not shown in the reference and which is bo-
liovad new and patontable. The claims do not cover merely
tho use of "old magnetic methods over and over again upon tho
oro, employing successively stronger magnetic fields as the
ore bee awes poorer”, as will be clear from the above descrip¬
tion of applicant’s process.
To sum up tho question, it may be said that appli-
[7/29/89
845
S.N. 319,401 Magnetic Separation]
cant's objoct i.s to obtain as a product from loan oros pure
iron in paying quantities. The Conkling protioss will not ac¬
complish this. Conkling will obtain a small quantity of pure
iron, and larger quantities of iron mixed with more or less
gangua • $0 will thus either loso a largo amount of iron in
tho tailings or his product will be impure, except a fraction¬
al part of it. Mow applicant gets all tho iron out and goto
it in a puro stato, and does this by tho dofinito stops of
soparation which ho claims. Tho malting of a dofinito divi¬
sion bctwoon tho pure iron particles and the composite par¬
ticles, is original with applicant; so is tho subsequent
separation of those composite particles from the pure gangue;
and then is tho especially essential stop, nothing in any way
analogous to •which is found in Conkling, of disassociating and
finally soparating tho component parts of tho composite par¬
ticles. More is a well considered process, each step of
which is now by itself, and certainly tho soquonoo of such
stops ought to be patentable. A process like Conkling's lias
just tho result which applicant soolcs to avoid. It cannot
obtain from a loan oro a paying quantity of puro iron. It
might bo useful with rich oros whore tho waste in tho tailings
nood not be considorod; or it might bo usod whore a pure
product is not cssontial. But it cannot accomplish appli¬
cant's result. Applicant docs not claim broadly fractional
separation, but only a definite kind of soparation, and a
treatment for a portion of the material which doos not form
part of any ordinary process of fractional soparation.
As has just boon held by tho Comnissionor in ex parte
tho addition to a process of any new step
[7/29/89 E 845
S.N. 319,401 Magnetic Separation]
which produces a useful .result makes the process a now and
patent able one. In the present case there is clearly a now
atop in the dissociation of the composite particles and the
advantageous result seems to bo clear.
In view of all tho facts it is difficult to soo where
in the reference forms a sufficient bar to the grant of appli¬
cant’s claims, and it is respectfully submitted that the ad¬
verse decision of the Board ought to be sot aside.

magnetic iron ores whereby the iron is graded as to purity, and the

the application wore not patentable. The following arc the
points on wiiicli the tppeal is taken:
Patent to Oonkling, 401,414, relied on by the Board
<3oe3 not anticipate applicant's claims. Said claims do not
cover merely re.crushing material separated magnetically from
the gangue and then passing it a second time through a magnet
ic separator, as indicated by the terms of the decision of
' *<» unuiouvi oujjuration which consists • in 3opa-
rating all magnetic particles, and lumps containing such part¬
icles, from all purely non-magnotic material at one operation,
then passing said magiotic portion through crushing or other
suitable machinery to disassociate iron particles in the mass
from gangue, and finally magnetically separating all magnetic
material ffom the gangue, is a different mot tod from the mere
Irogrinding of either of Oonkling 's impure products, contain¬
ing only a fraction of tho iron found in the whole mass treat¬

Drawing metallic particles out of a moving stream of
material by means of-magnets placed along the side of the stream,
is an old idea, shown in Edison's patent No. 238, 329 , dat ed .Tune
1,1890, and in patent of Guidon Conkling, No. 401,414, dated
April 16 ,1889. Edison's present improvement is a refihnmont
upon the old idea, using first magnets of a strength which draw
out the purely metallic particles, then crushing the Gaining
particles, and afterward repeating the drawing-out process. This
new refinement of the old idea is new and useful, but not every
new and useful thing is entitled tc/a patent. The present im¬
provement is simply the extension of the old idea, taught 1
intelligent observation of the old practice.
The decision of the exanin ers -in- chief is affirmed.

[7/29/89 E 845
!.N. 319,401 Magnetic Separation]
separate tho iron particles from all by one operation, for in
;hat case separation of tic ore into successive Grades would
be useless.
At no time in Oonkling'n process as carried out by
the apparatus illustrated, is tho ore separated into three
parts ns above indicated in connection with applicant's.;
process;* hence he docs not and cannot perform said process.
While in applicant's process tho pure Ganguo is separated
rn tho iron and magnetic tailings by the second stop of tho
operation, this is not accomplished in tho Conkling process
un.;il the third step, that,, is, until it has been subjected
to the third mar-net ic separation. Tho ga^uo, therefore,
unnecessarily adds to the bulk and weight of material passed
through tho final magnetic separator, (V at the right in
j. -0a. c. 3 o_ Conk ling s patent;, an by covering and impeding
free motion of tho magnetic particles makes a stronger
separator necessary .
It has already boon indicated that tho doubling
patent does not indicate what is done with tho separated ore
of several grad os. As is well known, it is oust unary in
dealing with iron ores to transport them, after separating
as much of tho worthless ganguo as can easily bo done mag¬
netically {ns in C oakling's process) or otherwise, to ra
proper furnace or plant, and tin re reduce them to the form
of pig iron or other form as desired. It is probable that
the magnetic ore obtained by Conkling is designed to be
taken from the separator to proper furnaces as above in¬
dicated. If tills be so, the purpose of the separation into
[7/29/89 E 845
:.N. 319,401 Magnetic Separation]
I successive Grades .is clear, viz., so that each grade may bo
properly treated, that is, may bo exposed to a proper tem¬
perature in tli o furnace, may be kept in the furnace a
proper length of time , etc. Further, if the above sup-
position is correct, in Oonkling's process a larfce amount of
worthless gangue would have to be transported from the
separator to the furnace with the second and third products
or grades of ore. According to applicant's process practi¬
cally no such gangue would have to be thus transported, and
this is a very important saving, as transportation is diff-
cult and costly.
As the result of applicant's process, all the iron
in the ore is obtained by this simple treatment in one high
grade product of comparatively small weight and mass, and
which can all be treated at once in a reducing furnace, while
as the result of Oonkling's process all the iron in the ore
may perhaps be obtained, but it will be distributed through
several products of different grades, of great weight and
bulk, and Which require separate treatment in the reducing
furnace. Wo have assumed in this argument that Oonkling's
apparatus would operate just as described and would be equal,-
ly efficient with the trajectory form. This would not be ; •
tVV°9 however . Experiment has shown that a magnet strong
enough to raise the pure iron parti olds vertically out of the
mass of ore will carry also large quantities of impure iron,
and even pure gangue. The latter is carried along by being
surrounded by iron particles which are attracted. To oom-
pare the process of Oonkling with that of Edison more readily
[7/29/89 E 845
'.N. 319,401 Magnetic Separation]
wo have shown them side by side in the no® mpanying sketch,
ffho sketch shows that by Conkling's process the iron obtained
would be divided; into several piles of different 3- ados, nark,
od First product, Second product and Third product on the
skdtch; it shows also the entire amount of gangue passing the
last separator belt. On the other hand, the sketch shows that
ifr the Edison process the iron obtained is all of one grade,
3 iron, and that the larger part of the gangue is entirely
out of the field of the last separator magnet.
The Examiners -in-Chicf say "the Examiner holds that
no invention would bo involved in the rogrinding of any of
these, impure products (of Oonkling) to got a product of great¬
er purity by a second operation". This phrase seems to us, to
show a misapprehension of what the process of applicant
really c onsists in, because even if Conkling described the
I rocru siding and roseparating of any one of his products he
would not accomplish vflm t applicant docs , and would not prao-
I tico the same process, and especially as defined in claims
5 and 4. ’
We must deny the vague and general statement in the
II first sentence following the claims in the Examiner's state¬
ment. The claims are not “merely for the application of
the woi-l known -methods of fractional soparation employed in
many arts" whatever that may mean, as stated by the Primary
Examiner. The claims involve the separation of the iron in
a particular way, and a definite treatment after preliminary
separation, as already indicated in the description of the

TO THE COMMISSIONER OP PATENTS,
S I R
In view of the eonBaiaaJLoner's decision in
thin case dated Decembor 5, 1391, and the issuing of the
patent to C. :?«■, Ball immediately thereafter (Mo. 405,349,
J dated December 15, 1391] the following amendment is made for
the purpose of securing an interference with the Ball patent.
On the 3rd page of the specification before the clause
'UYhat I claim is" insort the following: -
After the first two separations above described and before the
recrushing of the iron associated with gangue, which is the
/product of the second separation, the entire mass of ore is
divided, into throe parts, viz., (l) gangue containi^^^o^mag-
notic oxido; (2) magnetic oxide associated with gangue; and
(3) pure magnetic oxide with little or no gangue. These
three parts of the ore may be termed respectively "tailings",
"middlings" and "concentrato" , there being littlo or no iron
in the tailings, and a much greater quantity of iron in the
concentrate than in the middlings, which latter also con¬
tains a much greater quantity of iron than the tailings.
Erase the claims and insert: -
The method of separating magnetic ore from its impurities,
„ which consists, first, in crushing the ore, thon magnetically
[7/29/89 E 845

I then recrushing tho midcaings, which contain a per-eentage of
Iron, to mechanically dissociate the iron from the adherent
I gangue, and then magnetically withdrawing tho iron fran the
I recrushed material. _
An interference is requested with the patent of Ball

Statement of Grounds of Action of Primary Examiner Herein.
Before the
Hon. Commi ss ioner on Petition.
This application as it stands has been transferred from Div
XVI to Div. XXV, and the examiner will merely report the facts
appearing in the record.
After various actions had, this appli cat ion was finally
rejected as to all the claims , and the same affirmed by the Commis¬
sioner on appeal, Dec. 5, 1891. On July 18, 1892, an amendment was
admitted by the examiner then in change modifying the specifica¬
tion andj=substituting a single new claim accompanied by a request
for the declaration of an interference with patent No. 465, 349, to
one Ball, granted Dec. 15 ,1891, ten days after the unfavorable
action of the Commissioner upon this appli cation , the ajplicant's
new claim being the same verbatim as the 3d claim of Ball, The
interference was declared Aug.3, 1892.
The examiner's declaration of interference concludes as fol¬
lows :
"The Commiss ioner on appeal has declared the substance of the
issue unpatentable but as a patent was by mistake issued to Ball,
this interference is necessary."
The papers were duly forwarded to the Interference Division
but we re returned by Acting Examiner Orrickwith a letter calling

attention to rules 93,94 and 95, and to ex parte Meueci, C. D. ,
1890, page G5, and expressing an opinion that, an interference
should be declared. Examiner Bissing thereupon returned the
papers with a statement of reasons for his opinion that the inter-
fe rohce should go on. Thereupon Acting Examiner Orri ok, Sept. 8,
1892 referred the question to the Hon. Commissioner, who, on
Sept. 29, 1892, referred /the case to Examiner Bissing for specific
report as to whether the /claim of Edison covers the same subject-
•")
matt'er as that embraced ivn the claims which were before the Commis¬
sioner on appeal, and which were declared to be unpatentable in
) o ' v;
the decision of the Commissioner, dated Dec. 5, 1891. Sept. 27,
1892, Examiner Bissing furnished the report required and on Sept.
29, the Commissioner endorsed as follows:
"In view of the within report it seems clear that the
amendment of July 18 ,1892, was irregularly admitted (Rule 142) in
view of which all proceedings from that date are hereby vacated
and set aside. "
In pursuance of this, on Oct. 6, Examiner Bissing de¬
clined to enter the amendment and suggested the present petition.
It is believed that all the data material to the petition
have been stated, and the case is respectfully submitted.

Notary Public.
To all. whom j.+, may Noncorn,
j He it known that I, Thomas A. Edison, a citizen of
the United States, residing at Mewellyn Park, in the County
of Essex, and State of Mow Jersey, have invented a certain
{ now and useful Improvement in the Process of Magnetic Sepra-
l ration { Case No. 846) of which the following j.s a specifi¬
cation:
My invention relates to the magnetic separation of
ores, its object being to provj.de for the effectual con¬
centration of tli e valuable portion of oros in which magnetic
mid non magnetic materials are combined, and especially them
in which the particles of material are very snail and light.
Said invention is applicable to three classes of
ores, that Is to say (1) those in which the valuable product
is a non magi otic material, for instance auriferous pyrites,
roasted to make the iron magnetic, in which the gold iS the
material to be saved; (Pi) ores of magnetic iron ,in which the
iron is the valuable product; and (3) ores such as mangnnifi-
erous iron oros, containing magnetic iron mixed with oxide
of manganese , in wliich both the magnetic iron and the non¬
magnetic oxide are valuable. . ''"t:
I will describe +he use of my invention with each,
of these three classes of material. .
In many oros- o? gold of the kind above referred to
it is necessary to pulverize the ore very finely in order
to free tho gold and v/hen this is done it become of a clay¬
ey nature and clings together, and the particles of gold are
covered with fine m acetic particles so that the material
not only clogs up in tire Separator but in falling through
tha magnetic field the snail and concentrated magnetic pan-
| tides mutual Ty attract each other and inclose the go4«jhnd
thuB carry it mechanically so to speak into tho rocoptaclo
| for the magnetic material and so defeat the object sought,
vshich is to separate tire gold from the magnetic material.
Another difficulty with such fine light particles is that
they float awry from the falling sheet of material, indepen¬
dent of the magnetism. !ty my present invention X avoid
those diffi ail ties in the following way . I take the pulver¬
ised and roasted ore and sift it to a certain si so w to
I 125 mesh, and I add to this twice its weight 0f clean quarts
| sand of a larger size- say arch as will pass through a
| screen of 110 mesh but not through one of 100 mesh. I place
j the whole in a tumbling barrel, ouch as is used in foundries
I for cleaning castings etc., and in which I may also place
I a few tumbling jacks or blocks 0? quarts . After tumbling
Pn tho cylir,dor for a -few minutes the gold becomes freed by
attrition from clinging magnetic particles, and the fine ore
well mixed with the sand. The mixture being now passed
through the separator a vory clearly defined sheet of mo-,
terial is obtained with an exceedingly small proportion of
floating particles. I may here si, ate that the separator will*
I employ is of that class in which the material is caused
to fall in a wide thin stream past a magnet which alters
the trajectory or direction of falling of the magnetic par¬
ticles and that these fall into one receptacle, while the
non-magnet io material falling in a straight line enters
The magnetic particles are so separated from each
8.
oMar by the sand, that- there Is no mutual, attraction there¬
of and bo they do not mass together and carry the (rold par¬
oles among them, and in addition the gold has boon denned
from magnetic particles in the tumbling barrel. Therefore
the gold and sand fa'll together into die receptacle for non¬
magnetic material while the magnetic gaqnio falls on the
other side of the separating partition. Now I pass the gold
and sand through a revolving or other screen of 18b meshes
to the inch, and as only the gold (and any fine particles
of silica which have been in the ore) can pass through such
a screen, the gold is effectually snparatod from the sand. by
| ''his prodess I can readily and economically concontrate free
from pyrites the gold in low grade auriferous pyrites, and
i| the concentrate can be worirod in the ordinary manner as with
a freo milling gold ore.
I apply the process .in nearly the’ same way to the
concentration- of magnetic iron ores, in v/luch the magnetic
iron is the product to bo saved by separation from the non¬
magnetic gangus. ■
I crush the ore, say to such a size that it will all
pass through a 80 mesh sieve, and it is then best to separate
it into two parts of different sizes. All above 130 mesh
may go into one part and this is mixed with quartz sand of ;,
say 180 mesh sizojwhils the large material of less than' 130
mesh is mixed with sand of about 80 mesh. The proportion of
sand will vary from a weight equal to that of the ore, to
twice that amount, acco ding to the quality of the ore. Both
parts with their Band charges are worked in separate tumb¬
ling barrels to clean the iron particles and mix thorn with
8
| tho sand and th<y two then separately run through the gepa-
! rator.tho sand, a? before, diminishing tho amount of float
material and pro venting tho iron particles from carrying
particloB of gnngue with thorn and lessoning tho purity of
tho concentrate. AH the sand in tho tailings can ho regain-
ed by screening with a sieve of 1?,0 meshes, and used again
for the next operation. With "lean0 ores of magnetite in
large crystals, this process is not generally necessary be¬
cause the amount of silica in the ore furnishes a good mix¬
ture, Rvnn hero however the tumbling process is advantageous,
When however, the ore contains particles other than silica,
sucJt as talc, hornblende, phosphates, and lime, or when the
particles of magnetite am very snail and mixed with veiy
small silica or other crystals, high percentages of iron
cannot bo obtained by any ordinary process of magnetic sep-
aration.unless the ore is crushed very fine, and when this
is done there arise the difficulties above stated, from the
clinging of the particles and the mutual attraction thoroo f,
and make it impossible by the ordinary methods to produce
such high concentration as will make the working of such
ores commercially economical ;and also make it impossible to
dephosphorize ores rich in phosphorous down to a point sum
ficiontly free from phosphorous to be suitable for tho.Pesso-
mor process.
But by the enployment of my .invention- cleaning the
particles by attrition and the mixing of non-ma^netic matur-
ial such as quartz sand, with the material to be separated
theBe defeots are remedied, and it becomes possible to con-';
centrate poor ores containing large percentage of phosphoiw
ou9 and to reduce the phosphorous below the requirements of
tho Bos some}’ process.
In the ctise of a monganifemis iron ore containing
magnetic iron mixed with oxide of manganese (an pyrolusitn)
both materials are valuable. I grind tho ore raid sift it in
two nines as with the iron ore, adding to each part a proper
amount of sand, of a size larger than that of the pul yon- ;
ized ore. The ore is then subjected to attrition and sepa¬
rated magnetically an before. The iron is concentrated and
tho pyrolunite is found in tho sand, from which it is sepa¬
rated by screening.
If the iron ore is a sosquioxide end not magnetic
it is previously heated to drive off some of the oxygen
and, reduce .it to magnetic oxide.
What I claim is:
l. The improvement ijji tho process of separating mingled
magnetic nnd non-magnetic par hi cl os, which consists in mix¬
ing with tho same a quantity of finely divided non-mngnotic
material , such as sand, and then passing the whol e through

To all whom it may c on corn: -
Be it known, that I, Thomas A. Kdison, a citizen of tho
United States, residing at Ornngo , in tho CJounty of Rusox, and
State of flow .Torsey, have invented a new and usefuL improve- "'
ment in MAIJIMG OVIIUJ^RRS FOR PI0NOGRAM BLANKS, (Casa No. 85*).
of which the tollowin; is a specification'.
The object of my invention is to produce a ho Icier for
tran spo rtirg phonogram blanks on which intelligence has boron "*
recorded, which shall be light, and at the same time suffic-'
iontly strong to withstand blows or pressure it may receive.
My invention consists in the features of construction and
arrangement hereafter fully described and claimed.
In tho a ©company tng din. wing which illustrates the i won¬
't ion ,
Fig. 1 is ii central cross- sec tion through kit a cylinder -
with the cover in place thereon, and a phonogram blank con¬
tained in the cylinder. Immediately below this figure is a
•detail showing the form. of yielding cushion which is preferred
Fig. 2 shows a cross-section of the cover detached.
Fig. 8 is an inverted plan of the cover.
Fig. 4 is a cross-sec tion throujji the cylinder andpho -
nogram blank, on lino 4-4 of Fig. 1.
The cylinder is conpossd of two ooncontric tubes, prefer¬
ably of pupor, each tube being composed of several superposed' .
layers, properly oaneniud together. 1 is the out 9- tube, 2
tho inner tube, and 3 a space between them of suffioieut di-- "
tnonsi ons to roooivo tho p hon ogram tb 1 ark 0. The inner tube 1
is of such size that the phono gram blarik^w ill slide easily over
it. I’ll* tube then serves to support the phonogr em blank, this
preventing b train on the blank itself. It also holds the
-3-
blarilc from moving around in the cylinder' Ti-.e central sup¬
port 3 is not neoasegjplly in Ui form of a cylindrical tube,
since it ia evident that a support of different cross-section!
for example, triangular, the angles of the triangle a bearing:'
against the inner surface of the phonogram blonk, would serve*
although not equally well with the ttfce, ' The outer ttb o is
a little larger than the ou+zor 'airfare of the phonogram blank,
in order that the bl ai k way be slipped in readily, and so that
there may be no friction between the tibo and the phonogram . .
blank, which would tend to kR tat til ate or destroy the record "
impr esse d t hi' reon .
The cover- for this cylinder is composed of two concentric
flanges, 5, 7. The former fits the outer tube, and the latter
fits the inner tube. by this construction the cylinder1 is
tightly closed, and 'the central support is held from rtisplaoe-
ment. The upper end of the cylind er a d the outerjflange of"
the cov-r may bo provided, with screw-threads for fastening- ths
parts together1, but any^ desired moans m ay be employed for
this purpose, as, for example, a bayonet joint ccnneotioim, .
or an elastic band connecteid to the cover and to the box, as '
indicated by the dotted lines S. 1 -v,rhen' th is 1 ai/ter araarg c-
ment is usid the covt ccnbe pulled directly off but w ill
still be connected with the cylinder by the rubber band.
In the bottom of the outer tube is placed a yielding or ■
elastic oushion 9. This is p rof orably in the form of a ring
washer of felt, although it is evident that other materials
and o thee forms m»' be employed. A similar cushion is placed
in the spaco between the two fltnges 'of- the cover. ’.Yhen
therefore the phonogram blank is put in place its lower end
will rest on the first oushion, and when the cove1 is in plaa
t hopper end of the phonogram blail: will rest aeaindt the
sojcond oushion. This ar^an;; «mont proven ts all possibility
of any considerable d^iaajjroaiis longitudinal to v omen t of tho
bltu-k, sin d obviates the dat\j as* of chipping the ends of the
blank, whi oh might happen wit .‘out the cushions. ■■ ■
If the outer tube and the central support are both made
of paper, the completed device, of t-. size adapts* tojiontain

•jj v^' .
For ths oonstruotion of the hulls of ships, steel
I is a material which has lately oome into use on account of
its strength and lightness. It has been used particularly
for the hulls and armor of war-ships for these reasons and
^ because of its resistance to penetration. Experience has
I Bhown that the action of the Beawater upon the submerged
I portions of the hull of a steel Bhip produces a rapid
erosion of the exposed surfaoe, causing the weakening and
eventual destruction of the stool shell. Unless this dif¬
ficulty is overcome, the use of steel in the oonstruotion
| of ships' hulls seems likely to be abandoned.
II . . .
r The ^ri^ipal job j oct^ of (mj?) invention is to overcomo
this difficulty. (i have) found that the eras ion of stool
i seawater is wholly prevented by
sing tho oiroulation
of an electric current of considerable quantity through the
soawator between the steel and another submerged eleotrode,
the currant flowing in the direction to produce the evolu¬
tion of hydrogen upon the steel. To do this the Btool is
energy. (i^have) found by experiment that a ourrent of from
one-half to one ampere per square foot of surface is a suf¬
ficient current to accomplish the purpose, (^lthough I dgD
<^T~lTmiti’ employment of any * def ini to current 'c
bo long as it is sufficient in quantity to prevent the
erosion under the particular conditions. It may also be
desirable to use different strengths of ourrent with dif¬
ferent qualities of steel, since the rapidity of the action
and hence tho quantity of current t
iry to arroGt it is
I probably greatest with steel containing the moot carbon.
' /-rrt^,I'1(Ca/'ryinS ou^i^ invention, providg) the ateel
shipAwith ono or more dynamo oloctrio machines of suffi¬
cient capacity to supply the considerable current strength
required, which machines are preferably operuted by an in¬
dependent/ steam-engine. One pole of the source of cur¬
rent (the negative) is connected electrically with the
steel shell, while the other pole is connected with one or
more cables passing out through suitable ports and running
to submerged eleetrodea at a greater or loss distance from
the hull . These cables are well inarlined so that the
cables themselves will jr
t attacked vigorously by the
I current but only the eleotrodes, which will bo arranged for
replacement when eaten away enough to impair their utility.
While the Bhip is at anchor, these electrodes (one or more)
may be sunk to the bottom directly beneath or at a greater
or leBs diBtaneo from the ship, the oables running from
the ship to the electrodes under water, or the oables may
be carried on out-riggers above the water and the elec¬
trodes only be submerged, or even with out-riggers the
cables may run to the bottom at the ends of tho out-riggoro
to sunken electrodes. Many arrangements of the electrodes
will 8Uggos|_^themselve8 to suit the particular conditions,
and ^do not limit my/ invention ^to any particular ar-
ranganont: it being understood that tho purpose eubservod
by tho use of a number of electrodos or by looating ono
electrode at « distance from the hull, or by a judicious
fcnploymont of both of these features, Id to obtain as near-
Ily as praetieablo a uniform distribution of the current
ovor the entire submerged surface of the hull, thus in¬
suring the protection of the entire surface with the
maximum economy in the use of the electric current.
If it is desired to protect the ship while under
way, one or more trailing electrodos may be employed, al¬
though the protection of the ship vfhile at anchor is of
more importance.
Not only will the erosion of the ship's bottom bo
prevented by the employment of (my: invention, but organic
matter will not attach itself in the presenoe of a current
of the strength necessary to prevent rusting, and hence tha
fouling of the shell is in addition prevented.
Further, by keeping the surface clean, the skin
friction will be reduced and painting will be rendered
unnecessary.
So far as preventing the fouling of ships' bottoms
is ooneemed, the invention may also be usefully employed
with iron ships and with wooden ships sheathed with copper
or other metal, whore the erosive action is not present to
a destructive extent.
In the accompanying drawing forming a part hereof
Figure 1 is a oroos seotion of a ship's
hull showing my invention ap¬
plied thereto while at anchor;
and
Figure 2 is a side elevation of a ship's
hull showing my invention ap¬
plied thereto while under way.

Your petitioner. . THOMAS. A. . EDISON, . a . citizen of. the . United
States, ro8iding....a.t..J<lew.ellyn.....P.8rk.,.^.in.....thB . County . of Essex and
State . ofjfew.... Jersey, .
prays that Letters Patent may be granted to him for the . Improvement . in

set forth in the annexed specification; and he hereby appoints DYER & SEELY
(a firm composed of Richard N. Dyer, Henry W. Seely, D. H. Driscoll and

in the Patent Office connected therewith.
SPECIFICATION.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, -..THOMAS.. A. citizen of the
at MwftUyu Par*, .in
State., of New Jersey. . .
have invented a certain new and useful...:... .Improvement . ...in . .Magnet!
Belting (Case No. 877)
c . _

of which the following is a specification:
r . —
- a -
Til® object I have in view its to produce a form. of'
mnnotic belt, in" for transmitting pwer in connection with
magnetized pulleys, which will be simple and cheap in con¬
struction and efficient and durable in operation.
In the drfwingB —
.figure 1 id a top view of u section of the preferred fonn of
belting, showing tho magnetic pulley beneath it;
figure 8 is a perspective view of one of tho plates of tho
belting detached, showing suitable dimensions; and
Figure S is a top view of a modified form of the belting.
My improved magnetic belting is composed of platoo
of iron or steel hinged flexibly together by cross pins of
j JJ steel- The preferred form of the belting'is^ado up of
iron or steel plates A, each long enough to bridge the poloo
N Fi at the sides of one of the windings a of tho magnetic
pulleys over which the belt runs; one of such pulleys is
shown at 3. Kaoh plate A is ground concave on its inner
face so as to fit the surface of the smaller pulley. Two
parallel holes b extend longitudinally through each plato A,
and steel pins o pass loosely through those holes/ connecting
together as many plates, two or more, as are required to
give the proper width to tho bolt, these pins being secured-
at their ends in links d. The belting preferably has as
manj' of the plates A laterally as there are magnet windings
to the pulleys. Tho steel. pins _c pass through tho hole at
the right-hand end of one plate A and through the hole at
the left-hand end of the next plate, and so on through the
■alternate edges of as many plates as are used, while each
- 3 -
link d connects together »o pins proj acting from adjoining
plates. Thus the plates aro all froely hinged togothor
and a very flexible and durablo construction is produced in
which the otrain is distri but e cl between several points on
eaoh pin.
By the modified construction shown in figure 3,
the iron or steel plates C extend the entire width of tho
bolting, bo ing hinged together by steel pins e,. which pass
through two or more engaging lugs f g on tho meeting edges
of the plates, and distribute the strain between several
points along thoir length.
'That I claim is -
1. A magnetic belting composed of platoo
of magnetic material hinged together, substantially as •
set forth.
®* \ In magnetic bolting, the combination
of plates of magnetic Vat or ial and cross pins hinging tho
plates togothor, substantially as set forth-
In magnetic bolting, the combination
of platoo of magnetic material, axranged so that tho width
of the bolt will be occupied by two or more of such plates,
the plates being hing ed together at alternate edges, sub¬
stantially as set forth.
4. Un magnetic bolting, the combination
of plates of magnetic iWerial, arranged so that the width
the belt will be occupied by two or more of such plates,
and cross pine hinging cu'ch platos togother at alternate
edges, substantially as set forth.
plates of inaf5not,c material, arranged so that the width
of the belt will be bocupiurt by two or more of stioh plates,
oi'obu pins Jitncinu such plates together at alternate edges
and links each connecting tho ends of two cross pins pro¬
jecting from adjoining plates, substantially a s sot forth.

Th1? means for turning tho phonos ran blank an d i'or
movin" the recorder along the surface of the phonogram blank
are not shown, since they may be of any well-known or suit¬
able construction, and are not specifically claimed herein.
1 is the phonograph shaft; 2 the phonograph cylin¬
der; 3 the phonogram blank or recording surface; 4, the ring
or similar device supporting the phonograph diaphragm 5,
Lth a suitable speaking
i is a block or po n t
irding or reproducing p<
of which is the van<
parallel with, and’-f
, which extends substantially
ne face of the block 6; in
this face of the block is preferably formed a socket or de¬
pression 10, in which the vane moves; 11 is a light spring
secured at one end to the post anrjat the other end bearing
on tho arm 7 pressing the point toward the phonogram blank;
With this construction tho point will record proper¬
ly notwithstanding eccentricities or irregularities of the
I recording surface, since the vane offers practically per¬
fect retardation to any movement due to sound vibrations ow¬
ing to their great rapidity of alterations in movement, but,
on the other hand, the vane offers great flexibility or
absence of retardation to tho comparatively long and slow
movements due to esconti
•regularities of the
I recording surface; this makes it possible to record or re¬
produce from a very irregular revolving phonogram even one
which is oval in shq>e.
-4-
Tho form or the vane or. ret arming device above de¬
scribed differs from that described in ray patent above men¬
tioned, in that the vane is supported on an arm which occu¬
pies very little space at the center of the diaphragm, and
the lo nr arm carrying a vane at one aide of the diaphragm
is done away with .
£n figures 2 and 3 a modified form of retarding de¬
vice is ahfwn. Instead of a fan retarder for the recorder
pivotally supported on the post at the centre of the dia¬
phragm, a friction bearing is used for the same purpose .'6'
is aVievice, such as a screw the head of which presses
against one side of the post and which is adapted to make
the extensions' 6" clamp the recorder more or 'less firmly ,
thereby varying the friction between the recorder (or re¬
producer) and its bearing. Paid screw may also be made to
form the pivot of the recorder.
In use the bearing of the recorder or reproducer is
adjusted so that the friction at that point i3 very nearly
as great as the force of the spring 11. This form of re¬
corder or reproducer also responds to slow oscillations but
not to the rapid vibrations caused by sound or the sound
record. The movement given to the operating point by eccen¬
tricities of the phonogram blank being rather slow, however,
overcome the tendency to inaction of the retarding device
caused by the friction at the bearing, and so permit the
movement independent of the diaphragm. This device consti¬
tutes an improvement on the device described in' my patent •
393, 46 6, November 27-1888 .

TO THE COMMISSIONER OP PATENTS,
SIS;-
Reconsideration of claims 1, 3, 5, 6 and 7
in this application is requested. These claims embrace
special combinations not found in the patents, although the
patents do show devices somewhat analogous. Claim 1 speci¬
fies a recorder or reproducer pivoted at the center of the
diaphragm and having a retarding device also at the center of
tho diaphragm. Claim 3 specifies the angle lever, one end of
which has an operating point and the opposite end a retarding
device. Claim 5 specifies that the retarding device is ad¬
jacent to the block at the center of the diaphragm. Claim 6
calls for a pivoted recorder or reproducer supported by the
diaphragm and having a friction bearing. This is substan¬
tially different from a recorder pivoted on the ring carrying
the diaphragm and having a friction bearing.
Allowance is requested.

SPECIFICATION.
TO ALL WHOM IT MAY CONCERN:
... Be it known that I,„..THOmS...A..,EBI.SON.- . a....ci.t.iZen....o£.....the . .United.
JLn_iha .Qomjy. rnnrT nnrt
s.i§.te of New Jersey, _ _
have, invented a certain new and usefuL..Xmpro.v.ement . in.^honographa.,.
lCas.fi . H.Q., . SMI . . . . .
of which the following is a specification:
My invention relates to the recording and reproduc¬
ing devices of phonographs, and my object is to enable such
devices to work satisfactorily notwithstanding irregularities
m the surface of the phonogram blank or roco;ding surface.
Sometimes in the manufacture of phonogram blanks irregulari¬
ties or eccentricities occur in the formation of the sur¬
face, and sometimes the blanks become warped after manufac-
ture , and i£ proy
ot made to prevent it such irreg-
producing point and the diaphragm, which will interfere
with the recording or reproducing of the sound. This is
obviated by my rresont invention, which consists in an in-
proved form of apparatus by means of which the operation
is rendered substantially independent of such irregular it
of the phonogram blank.
In the accompanying drawing which illustrates the
(Figure 1 is a central section of a recorder, and
j Figure 2 is a plan view of the retarding vane,
i 1 is a phonograph shaft, 2, the phonograph cylinder,
and 3 the phonogram blank. The means for revolving the
phonogram blank and for feeding the recorder along the' blank
are not shown since they may be of any well known or suit¬
able construction and do not constitute, specifically, a part
of the present invention. 4 is a support for the diaphragm,
and is provided with a mouth piece, or a projecting tube to
which the flexible speaking tube may be at tached.in the or¬
dinary manner. 5 is a diaphragm having at or near its
-3-
conter a block or post 6, to which is pivoted the vane or
fan 7 which may be of any suitable shape. 8 is a post or
standard to which is pivoted the recorder or reproducer 9,
extending in an opposite direction from the vane 7, the
I free end of which bears on the phonogram blank. 10 is a
link or other suitable yielding or flexible connection be¬
tween the arms 9 and the vane 7.
It is found that in use the vane or fan described
constitutes a retarding device whoso inertia is such that
it will not be moved by the minute and rapid vibrations due
to the sound waves or the sound record but will transmit
such vibrations from or to the diaphragm, although it v/ill
permit movement of the recorder or reproducer independyn tly
of the diaphragm under the larger and slower motions due
to irregularities in the surface of the blank. This makes
it passible to record or reproduce from a very irregular
phonogram blank. It is evident that the sensitiveness
of the retarding device may be varied at will by changing tie
distance botween the pivot of the vane and the link ,or by
changing the form and size of the fan.
Having thus described my invention, what I claim i6:
1. The c onbi'nat ion of a phonograph di sphragm, a
retarding device connected thereto, a recorder or reproducer
l^the point oi which bears\or is adapted to bear on a phono-
blank, and a connection between the retarding device sd
and the recorder or reprodAcer , substantially as described.

pivoted thereto, a pivoted recorder or reproducer, "tl

|| post and extending toward the edge of the diaphragm, a re-
io.uler or reproducer pivoted at one side of the center of

ting in operative relation to a phonogram blank, and a con¬
nection between the vane and the recorder or reproducer, sub-
|jstantially as described.

In using this apparatus, the phonogram blank is
turned in the ordinary manner, and the recorder moves along
lengthwise of said blank, the- feeding devices not being
shown, since they may be of wall known construction and do
not form a part of tile present invention. The magnet be¬
ing supported on arm 4 moves along with the recorder. If,
now, the circuit 10 be made and broken by the telegraph key,
or be suitably varied in any other manner, the magnet will
be energized accordingly, causing the pad 13 to strike the
diaphragm' and r.o make a record oh the phonogram blank by
means of point 6. In this way thet . may not only be
received by . sound directly, but is also recorded and preserv¬
ed, and the record may be used afterward for' rej? eating the
message.

or mass 15, of carbon . or- other material, the electrical
conductivity of which is varied by pressure. The -anas 611 '
an dAG ' are insulated from euch other except as they are
connected through said material. One wire 16 is connected
to the lower arm, and a wire 17 is connected to the upper

soelcet 14 is a conducting material 15, as described in con¬
nection with figure 2. The circuit wires are connected in
the same manner as above indicated. The pressure with which
the arms bear on the phonogram blarfc is controlled by means
of the springs 20.
In the form shown in figure 4 the second or addition¬
al am O’ is dispensed with, both circuit terminals being
connected to a circuit -controller on the single reproduces7^
arm o. This circuit controller is formed as follows; In

circuit controller such as. shown at 15, figures 2 and 3, or
at 15‘, figure 4. As the phonogram is revolved the resist¬
ance of the circuit ,or the amount of contact- between the
circuit terminals, will be varied as the reproducing point
rides over the record. Those variations will be correctly
reproduced in the secondary of the induction coil, and will
effect a suitable receiver at the opposite ond of the line.

The element represented by numeral 6 is referred to as a

is objectionable, a single term should be used throughout.

Exactly what is meant by "the striking end of the levor
oeing maintained in the same relative position to the diaphragm"
as stated in claim 3, is not clearly explained in the description
since it is not apparent whether the perpendicular distance from
the diaphragm or the position relative to its boundaries is meant,
nor is the reason for calling the armature of the magnet 9 a
"sounder armature" made clear.
The utility of the pressor foot shorn in figure 3' is not
understood; it is thought such a construction would mar the record,

| the other patents, the diaphragm is the annature lever.
Claims 7, 8 and 11 have been canceled as per applicant's
request.
Claim 9, now 7, is again rejected on the references cited
^ for the reason that the guide rod and guide bar| are common o in¬

the arm is a recorder carrying arm, or that the combination i3 to

a recorder or a reproducer- and a phonogram blank as positive

SPECIFICATION.
TO ALL WHOM IT MAY CONCERN •
|: The invention relates to means fo rerecording
j and reproducing sounds, whereby a continuous record is
l| made on, or reproduced from, a' traveling strip or sheet
i phonogram blank, or on blanks of other form, the strip
| phonograph blanks preferably being of paper and having a
coating of wax like material.
In the drawing which illustrates the invention,
Figure 1, is a plan of the apparatus, and
Figure 2, a partial section of the same.
1. is a strip of paper or other material on .
the upper surface of which is wax or other material in
; which the phonographic record may be engraved or indented.
II .ffliis strip^is wound from one reel to another by any .suit¬
able mechanism, and passes over a bed plate 1' under the
| recording point. The forward movement of the strip,
which is slow, may be continuous or intermittent. 2.
| is a vertical shaft which is revolved by the same mechani-
ism as said reels, or by other mechanism, by means of a
| pulley 3. On this shaft are supported several phonogra-
| phio recorders and reproducers. Jn the drawing four re-
| corders, 4, and four reproducers, 5, are shown. The
recorders are supported by ttibular arms 6, and the repro-
! ducers by ttibular arms 7. The arms 6 communicate with
the box or casing 8, supported on a screw threaded sect-
| ion on the shaft 2. The box 8 has an upward extension in
j; the wall of which are openings 9. Around the extension
j- is a box 10 fixed in position and supported by aSsuitable
j: bracket 11. To this outer box is connected the speaking
I ' ’ -8-
tubs 12. The arms 7 communicate with a similar box S\,
having an extension and mounted on an oppositely a or aw
threaded section of the shaft, as clearly shown. The
boxes 8, 8' are connected by pins 13 or otherwise so that
they must revolve together, but shall be moveable longi¬
tudinally in relation to each other. ,14 is the hearing
tube connected to the lower box.
This ■ phonograph is operated in the following
; manner. Supposing, one of the recorders to be directly
over the edge of the phonogram strip at the loft in fig¬
ure 1. The propolling motor (not shown) is put in ope rat
f ion to revolve the shaft 2, and to move the record strip
• i along. As the recorder crosses the strip it mattes a
I record in the usual manner. At the same moment that the
| recorder passes from the 3trip at the right a second re-
! corder comes Onto the strip' at the left, but said second
recorder makes a separate track owing to the forward
movement of the atrip, which if the feed is intermittent
moves along just as the first recorder leaves the strip. ;
As the second recorder leaves the strip a third canes. . '
into place, and so on indefinitely.^^,-
phic record tlie operator holds the shaft 2 from rotating, I
and turns the boxes 8, 8' slightly, causing the arms j
carrying the recorders to bo raised from operative posit- j
ion, and causing the arms carrying the reproducers to j
move downward into operative position, owing to the
reverse screw threads on the shaft. The operator then
takes the hearing tube 14 and allows the 3haft 2 to re -
m f h
volvo when tho recorders will come into. operation one •
after another in the manner above described in .connect¬
ion with the recorders . Having thus described my invont-
what I claim is:
She combination in a phonograph having a, movable:
phonogram blank or recording surface, of two or more re-
i oorders or reproducers movable 'over said blank, one after
ji tilQ otil0r but ia a different track, substantially as described

Ser. No. 373,404, filed Dee. 3,1890, for Phonograph.
Commissioner of Patents.
An oath setting forth the fact that applicant had com¬
pleted the invention, as set forth in claims 9 and 11, before the dn'>
date of the British patent to Gale, should be filed, as the fact of
a caveat being on file is not evidence of a completed invention at
that time.
Claim 14 is not properly a method claim, but it sets
forth simply a function of the machine, and moreover, it is cer¬
tainly not such a method claim as should be al lowed in view of
the decision in the case of the Risdon Iron & Locomotive Works v.
Medart, 71 O.G. 751, and it is therefore rejected .

Pleaso find below a communication from the EXAMINER irioharje of your application
for Phonograph, filed Dec. , 3, 1 890, .sqrial,, number 373,404.
Applicants remarks ecncerning the requirement of
the office for an oath under Rule 75 in support of the 9th and
11th claims, have been noted, but the fonner action is thought
to be- right ,and is therefore insisted upon.
Among other things Rule>.75 provides that in such oases»the
appl leant shall make oath to facts showing a completion of the
invention" &o. x x x x and shall also make oath that he does not
know and does not believe that the invention has been in public
use or on sale in this country for more than two years prior to
. I
#373,404 2.
hie application, and that he has never abandoned the invention",
:T* As to the f irst.appl ic ant states in his caveat that he
desires further time to oornplete his invention, and this cannot
be c ons-idered* ae evidence that the invention was complete at the
date of'hie application therefor; neither can it be seen from
his caveat that the other : requirements of the rule are fulfilled.
Attention- is called to the decisions of tie Commissioner in
the cases of Ex parte lfanter,49 O.G.,733, C.D. ,1 889-218, and
Ex parte Hurlburt,52 O.G. ,1062, C.D; ,1 890, p. 135; \
In claims 7 and 8, there seems to be no patentable inven¬
tion whereby the record ingi.devide is moved over the record
surface, instead of the recording surface moving under the
recording device as illustrated in the patent to Gale, of record,
and unless this patent is overcane by an affidavit, they wil 1 be
rejected thereon.
Thomas A. Edison..

fsi'?...
Phonographs.
It ip noted the Examiner still -mihox^sto his position
that n er.'/or.t is not sufficient evidence of the completion of
an invention ns to overcome a reference under Kuie 75. In
applicant's opinion this position is so untenable that it
cannot be believed the Examiner vri.ll out applicant to the
nooossityo? having that question decided by tho Commissioner.
It seems to application that the question is one of identity-
pure and simple, and if a caveat shows the invention in con¬
troversy and is earlier than the reference, there ought not*
to be any question that such disclosure is a comple te-,- anticipa¬
tion of the reference,. •
Caveats do not nooessarily indicate that inventions
disclosed therein are entirely incomplete or only partlyin- -
OOmplete, as the Examiner appears to suppose. A caveat, may
show an entire completed invention or it may show an invention
fthat is complete only in parts. These are questions 'to bo
determined by in inspection and comparison of the caveat with
the application. In the present cose applicant insists that
tho envfip.t discloses everything that is common in the present
application and the reference to Gale..
The filing of the caveat was practioally a. notice to
the Pate.-t Office that the invention had been made by appli¬
cant, and that notice war, given before the date of the Gale
patent. The filing of an affidavit would simply be a reitera¬
tion of a- palpably- obvious fact, and applicant inists that if
is unnecessary.
In reference to that part of the Examiner's letter
where he says that applicant
"shall also make oath that he doe3 not know and
doos not believe that the invention has boon in publio
use or on sale in this country for more than two years
prior to his application, and that he never abandoned.!
the invention" '
the Examiner's attention is directed to the fact that these
requirements have been complied with in applicant's original
oath.
Very respectfully,
Thomas A. Edison.

of which is at the pivot, as will be clear without Air t her
description. With the arrangement shown the ampliw.de of
vibration of the diaphragm varies the distance which the

movement of the blank but does not move the point toward or
from the blank e'chept as it is moved by travelling in
the minute arc over which i-. passes. Since the blank
moves at the same tine that the recorder is vibrated it
will be evident that the record will be in the form of a
wavy line. I have found that the vibrations are more

TO THE COMMISSIONER OP PATENTS,
SIR :■
We find, on taking up thi3 case for appeal,
that the claims, particularly claims 1, 2 and 3, do not clear¬
ly set forth applicant's invention, and on careful considera¬
tion wo are satisfied that those claims as drawn are met by
the references cited. In order to properly sot forth appli¬
cant's invention and, as we think, avoid the necessity of ap¬
peal, we submit the following amendment with tho request that
it be admitted under Rule 68.
Cancel the third paragraph on page 2 of the specifica¬
tion, and substitute: -
In carrying out my method, I employ a moving recording sur¬
face, preferably in the form of a cylinder; a recording or
reproducing device supported adjacont to the recording surface
and in such position that the vibration of the diaphragm will
be toward and away from the recording surface; a recording or
reproducing point carried at one end of a lover, proferably
L-shaped, and pivoted to the supporting ring or frame for tho
diaphragm, and a connection between the diaphragm and tho other
end of said lovor. Thus, whon tho diaphragm is vibrated tow¬
ard and avmy from tho recording surface by sound waves, tho re¬
cording point will move through an arc of a circle at an angle
to tho direction of movement of the recording surface producinf
a record in wavy linos. -
Same page, lino 22, cancel word "angle" and substitute
- - - L-shapod - - -.
Cancel the claims and substitute. j
- 1. Tho method of recording or reproducing Bounds
consisting in moving a phonogram blank or phonogram beneath a
diaphragm whose vibrations are toward and away from such phono¬
gram blank or phonogram and causing the recording or reproducing
point to move through the vibrations of said diaphragm in an
arc of a circle at an angle to the direction of movement of th«
phonogram blank or phonogram, substantially as sot forth.
2. The method of reoording sounds on a cylindrical
recording surface consisting in rotating said surface beneath
a diaphragm whose vibrations are toward and away from said
surface and causing the recorder to movo through tho vibra¬
tions of said diaphragm, in un arc of a circle at an angle to
the direction of rotation of said recording surface, substan¬
tially as set forth.
3. A recording or reproducing device for phonographs,
having in combination a diaphragm, a ring or frame in which
said diaphragm is held, an L-shaped lever pivoted to said ring
or frame, said levor having a recording or reproducing point
at one ond and the other end of said lever being connected to
said diuphragm, whereby said point will be moved in the arc of
a circle when the diaphragm is vibrated, substantially as set
forth.
4. A recording or reproducing device for phonographs,
having in combination a diaphragm, a ring or frame in which
said diaphragm is held, an L-shaped levor pivoted to said ring
or frame, said lever having a recording or reproducing point

We are unable to see wherein the six-penny phonograph
anticipates applicant's claims 1 to 5. We understand that
in that phonograph the record was made direotly on a smooth
convex surface of traxLiJce substance. Said surface was not
first grooved, thereby leaving ribs or odges, and then the
ribs or edges indented or bent, as defined by applicant-.
We also fail to soe wherein the old tin-foil phonograph an¬
ticipates claim 5. The tin-foil blank had a smooth, and not
a ribbed, surface, although the holder on which it -was mounted
was provided with a spiral thread, but tills is evidently a
different thing from that defined in claim 5.
Claims 6, 7, and 8 clearly and positively define tho
cutting off tool of special construction, viz: ono adapted
to form tho ribs or odges on which the recorder can aot.
The cutting tools heretofore used have not been of this char¬
acter, so far as we know. These claims include the recorder
in addition to the cutting tool, or othor olomonts of tho
phonograph which aro sufficient to distinguish the combine-
tions claimed from such thinBa as are reforro d to in the

APPLICATION OP THOMAS A. EDISON
I METHODS OP AND APPARATUS FOR
RECORDING AND REPRODUCING SOUNDS
PILED DECEMBER 3, 1Q90,
SERIAL NO. 373,409,
ROOM NO. 221.
TO THE COMMISSIONER OP PATENTS,
SIR:
In the above-named applica¬
tion, the following amendment is submitted:
Cancel the sentence beginning with word Tt" last line
of page 3 and ending with word "described" line 2, page 4.
Canoel the claims and substitute,
1. The method of recording sounds with a phonograph,
consisting in moving a recording surface in proximity to a tool
for forming grooves therein producing ribs or ridges, and re¬
cording sounds on said ribs or ridgos, by means of a recording
device actuated by the vibrations of a diaphragm, substantially
as set forth.
2. The method of recording sounds with a phonograph,
consisting in moving a recording surface in proximity to a cut¬
ting tool for cutting grooves therein producing ribs or ridges
and recording sounds on said ribs or ridges by moans of a re¬
cording device actuated by the vibrations of a diaphragm, sub¬
stantially as- set forth.
3. The method of recording sounds with a phonograph,
consisting in rotating a cylindrical recording surface in prox¬
imity to a tool for forming grooves therein producing ribs or
ridges, and recording sounds on said ribs or ridges by means
of a recording device actuated by the vibrations of a dia-
phragn, substantially as set forth.
4. The method of recording sounds with a phonograph,
consisting in moving a wax or waxlike recording surface in
proximity to a cutting tool for cutting grooves therein pro¬
ducing ribs or ridges,and recording sounds on fcaid ribs or
ridges by moans of a recording devioe actuated by the vibra¬
tions of a diaphragm, substantially as sot forth.
5. In a phonograph, the combination with a recording
surface, of a tool for forming grooves therein producing ribB
or ridges, a recording device acting on said ribs or ridges,
and a diaphragm for actuating said recording device, substan¬
tially as set forth.
6. In a phonograph, the combination with a recording
surface, of a cutting tool for cutting grooves therein pro¬
ducing ribs or ridges, a recording device acting on said ribs
or ridges, and a diaphragm for actuating said recording devioe,
substantially as sot forth.
7 . In a phonograph, tho combination with a cylindri¬
cal recording surface, of means for rotating said surface, a
tool for cutting grooves therein producing ribs or ridges, a
recording device acting on said ribs or ridges to record sounds
and means for feeding said cutting tool and said recording de¬
vice along said recording surface, substantially as set forth.
8. In a phonograph, tho combination with a cylindri¬
cal recording surface, of means for rotating said surface, a
tool for cutting grooves therein producing ribs or ridges, a
recording device acting on said ribs or ridges to record sounds
an arm carrying said cutting tool and recording device, said
cutting tool being placed so as to act in advance of tho record,
ing device, and means for feeding said arm forward, substantial¬
ly as sot forth . - - - -
The six-penny phonograph is not a complete phonograph.
The recording surface is prepared by one apparatus and the rec¬
ord produced by another apparatus, and reproduction from such
record is made in still another apparatus. By applicant's
f-2-
method and apparatus, the recording surface is prepared and the,
record made in a singlo apparatus and the reproduction is also
obtained in that apparatus. The claims now presented are
also clearly distinguished from the Heysinger patent oited.
V/e believe the claims as now presented to be allowable.
Respectfully,
Attorneys for Edison.

Claims 1, 2, 3, and 4 are rejected on the ground
that they do not cover proper method claims, but merely set forth
the function or effect of the device. They are further rejected
as covering nothing patentable over what is shown in the patent
to Heysinger of record.
Claims 5, 6, 7, and 8 are rejected on the patent to Heysinger

of w!$ch the following is a specification :
'.Che present, invention relates to feeding devices
for phonograph recorders and reproducers, that is, devices
for moving the recorder or reproducer along over the phono¬
gram blank at the same tune that the blank revolves, The
ordinary way of accomplishing this is by moans nr a screw
shaft equal in length to the phonogram blank and having a
screvf thread of one-hundred or more threads to the indi.
and connected to the recorder
e producer by means of s
I but is objectionable owing to the large expense and to the
difficulty of manufacture of a screv/ shaft of the length and
fineness of thread required. The object of the present
improvement is to provide improved means for the purpose
entioned, and the inv(
i- the apparatus and

IMPROVEMENT IN PHONOGRAPHS
PILED DECEMBER 3, 1890,
SERIAL NO. 373,411,
TO THE COMMISSIONER OP PATENTS
SIR:
In tho above application, the follow.
ing amendment is submitted.
Erase the claims and substitute.
1, In a phonograph, the combination of a driving
shaft adapted to carry a phonogram blank or phonogram, a feed¬
ing screw for tho recorder and reproducer, and a pulley and belt
connection betv/een said shaft and screw, substantially as de¬
scribed .
2- In a phonograph, the combination of a driving
shaft adapted to carry a phonogram blank or phonogram, a feed¬
ing screw for the recorder and reproducer, sprocket wheels on
said driving shaft and said food screw, and a perforated belt
around said sprocket wheels, substantially as set forth _
It is believed that the claims now submitted will be
found unobjectionable. As will be seen, they are limited to
applicant's specific construction.
To anticipate a claim for a combination of elements it
is not mfnol.nl to shot, that tho individual element, hod been
used separately 1„ different 0„m,ecUo„s. In
M°e, a combination of contain olomenta is employed, and a. a
result a phonograph is produo.d which possessed inherent advan¬
tage utterly lacking in phonographs such as those eon, treated '
in ..oordanoo with the reference, cited. Thus, applicant la
.cabled to dispense with many of ths parts there accessary
utd thereby mate his machine cheaper, more durable and lose
liable to gat out of order. The decrease in the number of
parts employed, more especially the movable parts, causes a
corresponding decrease in the foreign sounds produced when the
device is in operation, such sounds tending to confuse the ar¬
ticulation of the reproducer. m a phonograph employing gears
as in the Brown patent the volume of these foreign sounds
would be considerable and the annoyance correspondingly great.
Furthermore, the Brown patent shows the phonogram blank car¬
ried on a separate shaft driven through gearing from a driving
| shaft. Applicant places his phonogram blank directly on the
driving shaft.
A comparison of applicant's construction with that of
the patents cited will disclose further differences between the
devices and further advantages in^tf^UiT^^tructure in view
of which an allowance is requested.

SPECIFICATION.
TO ALL WHOM IT MAY CONCERN:
Be it known that I. Thomas A. Edison, a citizen of the United
at I.legal-lyn Park, in the County of Essex ,- and
State of New Jersey,
have invented a certain new and useful _ Improvement jjg MagneticriOlutches
of^hich the following is a specification:
site end of said coil is connected by wire 9' to the wire
forming the coil in the seoond groove, and r,ho opposite end
of this xSkk is connected by wi re 9 , to the other ring 8',
the coils being thus in series with eaoh other, although it
will be evident that the series arrangement is by no means
'Srrao— wound that both conspire to produce a pole
esssnt iai . The coils are^of like polarity in the annular
mass of metal between the two coils. This is indicated by
the letter S in the drawing. The polarity in the metal on
the outsideof each coil would be of opposite polarity as in¬
dicated by the letters 0 K in the drawing. It will be under¬
stood that the rings 3, S' are current cullectors, there being
suitable brushes connectedto/the supply circuit and resting
in the grooves in said rings.
Facing this clutch member is a seoond member 10 which in
this instance is loose on the sane shaft being separated
therefrom by a hard metal sleeve 11. This member is also
provided with a smooth flat faoe which rests directly against
the face of the opposite member, us clearly indicated in the
drawing. By this arrangement the plate 10, which is’of iron,
serves as a keeper for the magnet and being in direct contact
with the poles thereof forms a magnetic mxx circuit of low
resistance, and causes the poles to hold said keeper withthe
greatest force possible. The plate 10 in the device il¬
lustrated forms a part of oris connected with the magnetic
pulley ll'. On the hub of this pulley are it two current col¬
lecting rings 12, 12' fran whioh the wires are led to the
coils in the surface of the pulley in the same manner as al¬
ready described in connect, ion with the clutch.
The form illustrated in Figure 3 differs from the spe¬
cies already described in form only. In this case one mem-

Llewellyn Park and Orange respect ively, in the County of
Waaax and state of New
and useful Improvement in Controlling.. Dsvi-ees -for-^Phono-
^aphs (ease No. 903) of which the following ia a specifi¬
cation:
The present invention relates to means for con¬
trolling or regulating the use of phonographs located in
public places, and the invention consists in an apparatus
the operation of which 1s dependent on the insertion of a
coin or similar token as hereafter set forth and as il¬
lustrated in the accompanying drawings , in which
Figure 1 is a plan view of our attachment and so
much of an ordinary phonograph as is nocessary to illustrate
the manner in which the attachment is connected therewith?
Figures 2, 3, 4 and 5 are views of Use coin ap¬
paratus looking from several points, as indicated by the
small arrows 2, 3, *1 and 5 on sheet 1;
Figure 1* is a detail view of a portion of the feed
• Figure 4a is a detail to be described.
In phonographs of the character above indicated,
we usually allow the reproducer to come to rest when it has
been used at the right end of the phonogram blank, and when
-3-
the 1 ponograph la to be again used, the reproducer must be
carried back to the oppoeite end of the blank, and then fed
slowly along the blank in the ordinary manner. in the ap-
pai a^ue oO bo deacribed, thiu return of the reproducer can¬
not bo effected until a coin hue been depoeited. 6 is a
slot in plate 7 adapted to receive a coin of predetermined
size, and communicates with the coin passage 8. The coin
tube or passage ie of the proper eize to receive the coin to
oo used. Extending into the paeeage at one edge iu a
lever 9, pressed forward by a spring 9', being pivoted at 10
and having a cam-shaped end 11. The upper end of thie
lover rests against the face of an insulating block 12, in
the surface of which at the left of the lever is a platinum
or other contact plate 13, to which the phonograph motor
circuit 14 ia connected. The other terminal 14' of the
mouor circuit may be connected directly to lever 9, said
lever and contact 13 thus forming a circuit controller for
the motor. The lover also reata adjacent to an arm 15
pivoted at 16, and having a projection or detent 17. 18 is
a spring pressing 15 forward. Below «
A
» 15 ia a second arm
19, pivoted at 20, and having on its end a pin 21.
Extending Into one eide of the coin passage (as
distinguished from its edge) is another lever 22, pivot od
at 23, and pressed by a spring 24. 25 ie a pin on this
lever to limit the distance which it may project into the
coin passage. 26 is a slot In the side of the tube tlirough
•ehleh the upper beveled end of lever 22 passes. The bevel¬
ed end 27 of another lever 38, pivoted at its upper end as
indicated at 29, figure 4a, extends into the coin passage
-4-
ihrough another .lot 30. The position of the slots 26, 30
is most clearly shown In figure 3, the slot 26 being lower
in the tube than the slot 30. Lever 28 is provided with a
Pin 31, against which block 32 bears; said block is con¬
nected with the sliding handle hereafter described by weans
of a plate or spring and moves with the handle. 33 i8 a
spring pressing against lever 28.
One side of the coin tube is cut array near the top
as shown at 34, figure 3, and over tiie opening is a door or
pivoted cover swinging from the top as indicated at 35.
Tills door ;ls weighted as shown at 36, 37, the weight 36
being adjustable.
33 ie a rod supported in bearings, which rod may
be moved downward by pressure on the knob or handle 39,
which extends from the rod, preferably being integral with
the body or casting 40 secured on said rod. This body iB
provided with two projection^ or lugs 41, 42, the former of
which extends through slot 43 into tiie coin passage, and can
move down and up therein ae handle 39 is moved in slot 44
(see figure 2). 44' is a plate to close tho latter slot.
The lug 42 projects in the opposite direction and normally
stands above a pivoted spring-pressed lever or arm 45 (see
figure 1) oarrled by the tilting bar 46, which lies under
the feed-arm 47 of the phonograph and when tilted serves to
raise the feed-arm from the feed-screw by muane of the
straight edge 46/, and if sufficiently tilted serves to
' -
bring an extension 48 on the feed— arm againBt the return

screw 49 The shape of tiie end 43 which bears against the
return screw is shown in figure la. The metal of tho arm
-5-
is bout into channel form, and both vertical sides of tho
channel bear against the screw, the edges -19' bains properly
inclined and shaped to fit the screw-thread. The feed-arm
4V is connected with the reproducer GO of the phonograph by
means of the usual guide sleeve movable on a guide rod or
in any other suitable manner. 40' is a spring attached to
the frame of the apparatus and to the body 40, holding tho
latter in its highest position when not in use. 51 is an
arm oarried by the reproducer or other movable part of the
apparatus and is adapted to strike and wove the pivoted
lover 15 when the reproducer reaches the limit of its
motion toward the right. 52 io a similar attachment at tho
opposite and of the 'Machine connected to the food-arm and
adapted to strike the pivoted lever 53, moving it against
the stress of spring 54. This lever may be arranged as in
the application of John P. Ott, 352,972, filed May 24, 1890.
A top view of the lever 53 is shown in figure 1.
The dark portion at the right Of 53 is an ext ansi on from tho
lever. 50 is a pivot at the lower end of said lover. 56
io a pin on the tilting bar adapted to rido by the extension
and to rest thereon. 57 io a vortical plate supported be¬
low the awn 45 and having an inclined or com edge 58. 59
is an ordinary phonogram blank driven by a suitable motor,
not shown, and 60 is tho feed-aerow. 61 is a dash-pot be¬
low the coin attachment, the piston being moved by an ex¬
tension of the rod 38 to prevent too rapid and uneven move¬
ment of the eliding body 40.
The apparatus constructed as above described is
used in the following manner: when a person desires to uso
till. phonograpn tW maiii'it) « hiokel or other predetermined
ooi„ into the .lot fl; tho coin mi* through the coin
passage, striking the inclined end 27 of the pivoted lever
23. It Will be, seen that the coin as it falls to this
position presses toward the right on said lover and toward
the left oh the pivoted door covering the opening in one
side of the coin passage. The weight of the door and the
tension of the spring pressing against 23 are so adjusted
that when the proper coin is deposited, the weight of tho
coin will move lover 28 back but will not move tho door or
cover on its pivot. The coin passes partially by the end 27
and comes to rest with its lower edge resting against tho
lower cornei’ of the end of lever 22, the edge of tho coin
being also just below tho bottom of tho door opening, as in¬
dicated by the dotted circle in figure 3. The operator
then presses down on the handle 39 overcoming the force of
the spring 40* and moving the body 40 downward. The lug 41
moving in the slot 43 Strikes the top of the coin, pressing
it down in tho coin passage and bringing it against the cam
11, which extends into one edge of the passage. As the
handle is moved down still further, the lever 9 is thrown
toward the left until its upper end passes the catch or de¬
tent 17, when said lever 9 snaps onto plate 13 and thus
closes the phonograph motor circuit and the coin drops en¬
tirely through the passage into a proper receptacle. The
lug 42 during the same downward movement pressed against tho
upper iflee of the arm 45 moving it downward, moving the
tilting bar 46, raising the food-arm 47 and bringing the ex¬
tension 48 against the return screw 49, whereby the repro-
.-7-
duaar ia fed rapidly toward the left. As the tilting bar
is moved in the manner described it is hold up by the oat oh
or detent 53. Just before the lug 42 carries the arm 43 to
ite lowest position, said arm strikes the inclined face or
cam surface 58, and as it continues to move downward io
carried to one side against the force of its spring until
said arm 45 is carried out from under tiie lug 42. This al¬
lows the tilting bur to resume its normal position when re¬
leased from the e.ateh 53. This release ia effected by
arm 52, which moves with the reproducer, at the end of its
.movement toward the loft, and as the tilting bar resumes its
normal position, the feed-arm comes in contact with the food
8 crew , and the reproducer is fed slowly over the phonogram
blank to reproduce the record thereon. When the repro¬
ducer reaches the end of the phonogram, the arm 51 strikes
the lever 13 moving It on ita pivot 13, carrying the tooth
or catch 17 from behind the arm 9 of the circuit controller,
thereby allowing it to snap back to ita original poaition.
It might happen under certain c ircuinst ances that
the handle 39 would not be pushed entirely down by the user.
In that case It is possible that the coin might come to rest
against the cam 11 in such manner as to hold the arm 9 and
to prevent it from returning when released as just described.
In that ease of course the phonograph motor would continue
to run, thereby wasting battery power and injuring the ap¬
paratus. To obviate this difficulty- the lever 19 is pro¬
vided. When the arm 51 strikes the lever 15 it moves said .
lever against the pin 21, turning lever 19 on its pivot 20.
It will be evident that the lower and of said lever 19 Yd.ll
proas the am 9 away from the -outset 13, thus tending to
hold the elk-suit open. => ^9-'( /r-w

Should any article be deposited In the coin
•‘ leaa weight titan
toin for which the in¬
stilment Is adjusted, It will be insufficient to move the
lever 23 back against tlie force of its spring when said
article strikes the inclined end 27, and when the handle 39
is moved down, the lug pressing on the article will cause i
to ride down the inclined face 27, swinging the door open
and allowing the article deposited to pass out at one side
of the coin tube. Should a coin be deposited of smaller
diameter than the apparatus la cons true tod to receive, it
would not move the lever 9 sufficiently far to pass by the
detent 17, and the small coin would pass through into the
coin receiving bo* without closing the circuit.

The insertions in claims 4 and f> place these claimB
outside the scope of the lilasB and Arnold patent. In this
patent the coin is not depressed by manually operated mechian-
I ism but by an electrically actuated sheave or roller. It is
maintained that this patent is not an anticipation of claims
V and 8. There is absolutely no "safety o iroui t breaker"
in the (Jlass patent. It should be borne in mind that this
safety circuit breaker is a device addition el to the main
circuit breaker. It is admitted that in the Class con¬
struction there is, and necessarily must be, a circuit braak-
but. that there is no safety circuit breaker
trJ(in addition to the catch to hold the circuit dosed and
releasing device for said catch is apparent at a glance.
Claims ? and 8 are not. met and should be allowed.
The "rigid arm detent" of Class & Arnold is not an
equivalent for the pivoted spring actuated detent lever of
claim . Applicants' contacting mechanism is considerably
in advance of the mechanism of this patent. It is quiok-
aoting and positive. The contact is either made or broken
in an instant. In other words, it is a snap action ns dis¬
tinguished from the fiction of the contact maker and breaker
of the patent in question wherein the relation between the
contact pieces is slowly, gradually changed from disconnection
to contact. This is the very difficulty -<hioh was overcome
in the snap switch, it having been found that the gradual
bringing together of the contact pieces caused the current to
stumble and spark and woro out the contact plates. Appli¬
cants' positive action is manifestly superior to the mechanism
of the patent, and we therefore contend that claim 6 should be
allowed.
Claim 9 has been limited to a lug adapted to actuati

ROOM NO. 209.
in the above application, amend claim \
inserting after the word "breaker" in the fourth line thereof,
~^===sy^adapted when the phonograph reproducer reaches its
limit of motion in one direction to break the motor circuit,
["ev.en though a coin remain in the coin passage^- _
> .v^^Amend claim 8 by striking out the words "to actuate
the circuit controller", and substituting in lieu thereof,
‘when the phonograph reproducer reaches its limit of
ation in one direction to break the motor circuit, even though
coin remain in^the-_c.Qin passes - - -
It is submitted that the above claims as amended clear
ly distinguish from the construction described in patent to
Glass & Arnold cited, in which the motor circuit remains un¬
broken as long as a coin remains in the coin passage. The
advantages in a machine of this class of the employment of a
device which insures that the motor circuit shall bo broken at
the proper time Irrespective of the position of the coin, are
apparent, and as no device of the sort is shown in the refer¬
ences of record, we believe that applicants are entitled to pro¬
tection for this feature of their invention. The serious re¬
sults which might follow a coin's remaining in the coin passage
were evidently appreciated by Glass & Arnold, and to avoid, as
far as possible, the danger of such an occurrence, they employ
a complicated arrangement consisting of rollers, band and pul¬
leys. It might easily happen, however, that from some varia¬
tion in the shape of a coin, or some slight defect in the
mechanism, for example a too great smoothness of the rollers,
that the coin would still remain in the coin passage. Appli¬
cants avoid the oomplioationsof the Glass & Arnold device, and
at the same time provide with absolute certainty that the mo¬
tor circuit shall be broken at the proper moment.
A reconsideration of claim 6 is respectfully requested.
The advantages of applicants' means for making and breaking
I the motor cirouit, over the means employed by Glass & Arnold,
are apparent on a comparison of the action of the two devices.
In the latter device the contact is gradually made as the two.
parts P and E come together, and then before being fully es¬
tablished is almost, if not fully, broken as the hook P pa860a
over the projection of E. The breaking of the circuit is
also effected gradually by moving the hook P down and clear '
of E. In applicants' device the flexible lever 9 passes over
the projection 17 on the arm 15 and snaps upon the contact 13,
when the connection is at once and fully established. Wien
the circuit is to bo broken, the lever 19 moves the arm 9 in¬
stantly clear of the oontact plate 13, and a movement of the
arm 15 then allows the arm 9 to pass clear of the projection 17,
Ganoel claim 9 and substitute the following:- _ _
The oombination in a coin controlled phonograph, of a
tube adapted to reoelve a coin, a contact lever extending
within said tube and in the path of a ooin within said tube,
a sliding rod within said tube, and a handle for operating
same, a oirouit terminal with which said contact lever makes
oontact to complete the oirouit to an electric motor, said
oontact lever being forced into oontact with said terminal by
a coin and said sliding rod, and a detent for holding said
contact lever in contact with said terminal, and a releasing
device for said detent, substantially as set forth.- . -

| APPLICATION OF THOMAS A. EDISON
I IMPROVEMENT IN PHONOGRAPHS
JfIIjED FERRUARY 9, 1891,
[SERIAL NO. 300,713,
TO THE COMMISSIONER OF PATENTS,
I sir:
In tho above case, we submit the follow-
ing amendment :
j Erase the 8th, 9th and 10th claims.
With reference to the 1st and 2nd claims, it is
submitted that in view of the fact that the flexibility of a
belt of parohmentlike material is such as to prevent any noise
iwhioh would interfere with tho recording and reproducing of
sound by the phonograph, the use of such a belt produces a
new and different result from that produced by those formerly
in use, and the substitution is, therefore, a patentable one.
The case is not of the oharaoter of those referred to in the
Official letter of April 30th, 1891, but comes under the rule
expressed in Washing Machine Co. vs. Lincoln, 4 Fish. 379, in
which a roller covered with rubber was allowed to be patenta¬
ble over one ooversA with cloth, because of the superiority
of the former in a washing maohine.
The 3rd and 4th claims cover the invention of employing
an enclosing case for the pulleys of the phonograph. It is
not understood why these claims are considered as being for
"a mere aggregation of elements*. If these claims are to be
rejected, it is requested that references shall be oited.
-2-
II Whether or not a claim is for an aggregation of parts depends
upon the prior art, and it is believed that this ground of
rejection ought not to be taken unless the prior art shows
that each of the elements of the claims is oia for the same
purpose, and in such a way that their combination is not pat-
I entable .
It is thought that references should bIbo be cited
j| f or the 5th, 6th and 7th claims. The mere statement of the
Examiner that in his opinion the claims do not involve invon-
tion over something else which he ha6 in his mind, but to
| which no reference is given, does not seem to be sufficient
information to enable the applicant to judge of the propriety
of further prosecuting the claims. We submit, however, that
these claims are for mechanical structures different from
anything heretofore in use so far as the record shows, and
that they produce new and useful results in the operation of
the phonograph . Such slight mechanical clungos are commonly
made the subject of patents in other classes of machinery, and
it is not understood why they may not also be patentable with
the phonograph.

JhON. COMMISSIONER OF PATENTS,
sir:
Thu above application is hereby amended
JaB follows: —
^ Erase olaims 1 and 2, and substitute the following.
R phonograph, the combination with a feed-
I screw and phonograph shaft, of pulleys connected with said
screw and shaft, and a belt of parohmentlike material, sub¬
stantially as set forth.
u phonograph, the combination with a feod-
jscrew and phonograph shaft, of pulleys connected with said
t and shaft, and a belt of parohmentlike material perfor¬
ated at regular intervals, substant ially as set . .
Erase claims (3 and 7.
The bolt is now made a positive element of the combin-
jation, and with the remaining elements of the claim constitute)
i entirety, to wit, a phonograph. It is, therefore, sub-
(litted that those claims should be allowed in the present ap-
lication and the division heretofore required Bhould not be
nsisted upon.
Claims 3, 4 and 5 are not met in the references cited.
Applicant is perfectly willing to admit that an en- '
slosing case for gear wheels has been used in olothee-wringors.
Ihis fact til ono , however, does not preclude patentability in
jthe present case. The claims in which this construction is
.included we limited to certain specific features of isppli-
:j cant's construction. Manifestly, it is not sufficient to
Anticipate this construction to show that a single element,
or, in fact, all of the elements individually, had been used
in different connections and for non-analogous purposes.
As was said by Judge Coxe in a very recont case, to wit, John¬
son v. 42nd St. etc. R. R. (33 pod. Rep., 499),
"It would be as irrational to charge an author who
has produced a sentence of surpassing power and beauty
wuh plagiarism because the words which he employs have
long been found in the lexicon, as to overthrow a patent
lor a new and useful combination upon the ground that its
separate elements were old."
That no analogy exists between a clothes- wringer rind
a phonograph is obvious.
The enclosing case of these claims performs a new and
useful function in this art. In phonographs of the present
day, tt wax cylinder is used, and the recording style operates
to remove from the periphery of the cylinder chips or shavings
Of the material. It is usual to provide a receptacle for
tjhese loose particles of wax, but more or less of them will
not bo deposited in such a receptacle but will Bottle upon
the various parts of the machine, and accumulation means a
njore or less sluggish and inexact operation of the machine.
Added to this is the necessity of preserving the working parts
of the device from dust and other foreign matter. Applicant
hlpe sought in his present construction to protect the pulleys
and their connecting belt by means of enclosing them in a case.
land has provided that ease with a removable oovar, in order
that the parts may be reaohod and re-adjusted if necessary.
An enclosing case is desirable in almost every type of phono-
Graph, but in the present type, wherein a perforated belt is
used, it has become more than desirable — it is a necessity.
'.Ve, therefore, submit that the claims referred to are
for a construction which produces a new and useful result,
and they should, therefore, bo allowed.

TO THE COMMISSIONER OP PATENTS,
SIR:-
In tho above named application the follow¬
ing amondmant is submitted:
Cancel the first paragraph, page 2 of the specifica¬
tion and substitute: - ——/The object of my in¬
vention is to provide a driving connection between the phono¬
graph shaft and feed screw of phonographs whereby the vibra¬
tions of the phonograph shaft and driving motor will not bo
communicated to the recording or reproducing devices with
which the feed screw is connected. This I accomplish, by
providing tho phonograph shaft and food screw with sprocket
wheels and connecting tho same by a perforated belt made of a
soft yielding material like leather, the phonograph shaft be¬
ing driven by a belt connection with the source of power whioh
is preferably an electric motor - _
Same page, cancel lines 11 to 2B, both inclusive, and
substitute: - .—/The phonogram cylinder 1 is
carried by the phonograph shaft 2 which Is provided with a
driving pulley 2a for the usual belt connection with the driv¬
ing electric motor. Parallel with shaft 2 is the feed screw
3 having a sprocket wheel 3a, whioh is driven by the sprocket
wheel 3b on shaft 2 through a perforated belt 4. Por the
perforated belt I employ animal membrane such as untanned
skins, bladders etc., or other parchmentlike materials, leather
or the like. These materials I find preferable to stool be¬
cause being soft and yielding they do not transmit vibrations
whioh affect the sensitive recording and reproducing devices,
and because the perforations In a belt made of either of the
materials named stretch to a greater or less extent and engage
the sprockets more readily than in the oaee of a steel belt.
An ordinary belt and smooth pulley connection between the
phonograph shaft and feed screw could not be used, since any
slipping of the belt would produce variations in speed of the
feed screw relative to the phonograph shaft, resulting in the
making of an imperfect record or a poor reproduction of a good
raoord. On the guide rod 5 works n sleeve 6 from one side of
which projects the recorder or reproducer oarrying arm 7 and
from the othor side projects the feed arm 8 oarrying the nut
adapted to engage with the feed screw,/-- _
Insert the following claims: . . -
1. In a phonograph, the combination with the blank oarry¬
ing shaft driven by power, of a food screw for the recording
or reproducing devices driven by the blank carrying Bhaft and
connected therewith through sprocket wheels and an endless
sprocket belt of soft yielding material, the movable arm oar¬
rying the recorder or reproducer, and a nut connected with
said arm engaging said feed sorew, substantially as set forth.
2. In a phonograph, the combination with the blank oarry¬
ing shaft driven by a bolt oonneotlon with power, of a feed
screw for the recording or reproducing devioes driven by the
blank oarrying shaft and connected therewith through sprooket
| wheels and an endless sprooket belt of soft yielding material,

June 15/1895.
patents of Barnes and Morse, also cited against these claims,
show two forms of perforated belts for sprocket gearing. In
both these forms, the perforations of the belt are made oblong
in order to insure their registering with the sprockets of the
pulleys. This form of perforated, belt is not adaptod for use
in a phonograph. It is well known that the perforations of
the belt in sprocket gearing will not register with the sprock¬
ets of a wheel unless the perforations are made oblong, but
with such perforations the bolt is liable to slip slightly, as
all the sprockets which project into the perforations of the
bolt at any one time do not positively ongage the belt; and
as one sprocket after the other recodes from the belt, it is
liable to slip until another sprocket positively engagos there¬
with. Such a slip of the belt is of course very slight, but
is enough to result in the production of an imperfect record
on a phonograph.
In the operation of the phonograph, it is absolutely
neoessary that the feed-screw must bo drivon at a constant
rate of speed in order to aaoid inaccuracies in the production
of a record or in ttfo reproduction thereof. Thus, in apply-
lng sprocket gearing to a phonograph) It waB necessary to pro¬
vide a belt which would drive tho feed-screw without the
slightest clip, and at the same tlmo Insure the accurate
registering of the sprockets with the perforations of the
belt. Hr. Edison found that he could accorapliah the desired
result by employing a belt of soft and yielding material, so
that the belt would stretch between the perforations, insuring
the proper registration of the perforations with the sprockets.
Thus Mr. Edison secured a positive engagement botween the belt
and all the sprockets which register with perforations at one
time, so that there can be no slipping when tho sprockets re¬
cede from tho belt. This is new with Mr. Edison and has
never been proposed, so far as v/e are aware, in any clae6 of
machinery.
A reconsideration la requested.

perforated at regular intervals, such perforations neing of

NO'iH:- a reconsideration of the first four' claims is
-1-
requested. It is manifestly new to make the connection of the
driving parts of a phonograph in tho form of a soft and yield¬
ing holt. Such a bolt is not shown in -ho prior art nor in any
Of the references cited by the Bxnminor outside of tho art.
Tho peculiar advantages of applicant's invention are
brought out fully in the specification, in which it is statod:-
"These materials I find preferable to steel,
because being soft and yielding they do not transmit
vibrations which affect the sensitive recording and re¬
producing devices and because the perforations in a bolt
made of either of the materials named stretch to a
greater or less extent and ongage tho sprockets more
readily than in the case of a steel halt."
In tho decision of tho Cor.Sid ssi'Oijor in ex parte Grayson
;.uid CrecoHus relied upon by the Sxaminer, the doctrine is
laid down wi th much elaboration that the more substitution of
a known material to accomplish a known result will not amount
to invention. This, of course, is fundamental law. 'Ibis
.doctrine does not apply to the present case, as applicant does
not substitute ono old material for another for accomplishing

Dear Sir:
Reconsidering the matter of paying final fees on the
two allowed Edison applications, I would advise you to pay these
fees, although the railway case may not be assignable to the General
Electric Company. I am advised by Mr. Fish that the Company
veill be responsible for the fees in both cases, and that the matter
of assignment may be left until the patents issue.
